In August 2021, a mysterious package from Sarasota, Fla., showed up in Nicole Archer’s mailbox in Manhattan.

Dr. Archer hurried upstairs to her cramped Chelsea apartment with the thick envelope in hand and tore it open at her dining table, revealing a legal document she had wondered about for months.

She knew that a beloved college professor had bequeathed her something in her will. She was expecting a modest gift — enough money for a fancy dinner, perhaps, or one of the beaded bracelets the professor liked to make by hand.

But when Dr. Archer, 49, saw the number on the last page — $100,000 — she thought there must be a misplaced decimal point.

“I truly, honestly believed that I read it wrong,” she said. “I remember following the number with my finger, making sure I understood how many zeros it was.”

At about the same time, 30 other people across the country received similar letters, sent at the behest of a professor whose class they had taken years earlier.

Over 50 years of teaching art history at New College of Florida, Prof. Cris Hassold had carved out an influential but complex legacy. She referred to her students as her children. She hired them to clean her home — a disturbing hoarder’s den. At times, she humiliated them in class.

But the students who knew her best described her as a singular force of good in their lives. “The cult of Cris,” as one described it, lives on in her 31 favorite students, who inherited her intensity, her quirks and, in the end, her life savings.

A Backdrop of Counterculture

New College, a small public honors college in Sarasota, on Florida’s Gulf Coast, was known for attracting gifted students who could not afford a private liberal arts school but who sought a rigorous course load in a relaxed, sunny environment.

It became a center of counterculture where gender studies courses filled up quickly and students wandered the campus barefoot, experimented with drugs and organized sex parties.

Courses were demanding. Professor Hassold detested textbooks and assigned 150 pages of weekly reading from dense, primary sources by writers and critics like André Breton and Rosalind Krauss.

Inside the dining room of the century-old Old Caples Mansion, which looks out onto palm trees and the vibrant blue hues of the Sarasota Bay, Professor Hassold would draw the shades, shutting out the sunshine in favor of focused darkness. A dozen students each semester would sit around a table for hours, discussing the postwar femme fatale or analyzing a painting’s brushstrokes.

Andrea Bailey, 47, who is now the director of American Women Artists, a nonprofit organization, was confident in her ability to write about art — until she enrolled in one of Professor Hassold’s art classes in 1995. Ms. Bailey kept one especially scathing review of her take on a van Gogh painting.

“Her conclusion that the woman in ‘The Straw Hat’ is an aristocrat is simply wrong,” Professor Hassold wrote in Ms. Bailey’s academic file on Dec. 8, 1995. “I do not understand how she could have read about the works and gotten it so muddled.”

The students who were not intimidated by Professor Hassold’s withering style were the ones most likely to be granted admission to her inner circle.

Dr. Archer is now an associate professor of art history and gender studies at Montclair State University in New Jersey. She recalled walking into one of those dimly lit sessions in 1995 as an ambitious but directionless freshman and seeing Professor Hassold behind a pile of oranges that she had harvested for the students in her surrealism class.

“Doesn’t your family eat all of the oranges?” a student asked.

“I don’t have a family,” Professor Hassold said.

“You’re not married?”

“What would I do with a husband?” Professor Hassold, who grew up in Louisville, Ky., scoffed in her Southern drawl. “That would just be a pain in the neck.”

The offhand comment stuck with Dr. Archer. “It was kind of like the most amazing moment I had ever had,” she said. “She is just herself. It was a type of woman I had never met.”

A Home That Revealed a Secret Past

The professor and her students strengthened their bond during long, informal dinners.

Over potstickers at the Cheesecake Factory or French onion soup at a local bistro, Professor Hassold gossiped with them about rival art professors or recalled adventures with old boyfriends in New York. She expressed dismay over her belief that New College was losing its liberal, countercultural spirit — a shift that would become more pronounced decades later.

Professor Hassold was always digging into her students’ aspirations.

“What do you want to do and how do you get there?” her students remembered her asking. “Who do you like to read? Where do they teach? They teach abroad? How do you save up the money to go?”

These dinners, Dr. Archer recalled, “were these fun spaces where you could imagine a life for yourself without restrictions.”

Many students wondered, however, why Professor Hassold never invited them into her home.

Ryan White, who enrolled in Professor Hassold’s film noir class as a freshman in 2003, would come to understand. After he grew close to her over the semester and the following years, she asked him to help her mow her front lawn — an apocalyptic jungle of ferns and shrubs — and tidy up inside her home.

Mr. White, 45, who now runs a New York City-based knife sharpening company, recalled that it was a “nightmare.”

Cans of food, muffin tins, office supplies and a library’s worth of art history books cluttered every corner of her home. Stacks of papers spilled onto her bed. A guest bathroom had been rendered useless for a decade because boxes of papers prevented the door from opening.

Her neighbors had complained, and welcomed the effort by Mr. White and other students to clean up her property, delivering lemonade as a gesture of gratitude.

“I’m going to need this someday,” Professor Hassold would say as she held up an old article, Mr. White recalled, perhaps one about Stéphane Mallarmé’s impact on cubism.

“You haven’t seen it in 40 years,” Mr. White would respond.

Katie Helms, 47, of Kingston, N.Y., who graduated from New College in 2003, gained insight into Professor Hassold after they fell into a deep conversation about their parents.

Ms. Helms, now a business consultant and doctoral student in education, made a habit of reading Professor Hassold’s hundred-page assignments multiple times, making her one of Professor Hassold’s favorites.

One night as they drove to dinner, Ms. Helms said, Professor Hassold recalled returning home from the University of Louisville to find that her mother had thrown away all of her daughter’s belongings. Ever since then, Professor Hassold held onto everything.

It was likely just one factor behind a hoarding problem that eventually rendered her home unlivable. Instead of parting with the detritus, Professor Hassold built a second home on her property.

“She wasn’t very good at letting things, or people, go,” Dr. Archer said.

‘She Adopted Us’

The youngest of 12, Ms. Helms received little attention growing up. That changed when she met Professor Hassold. For the first time, Ms. Helms felt unconditional acceptance for everything from her smoking habit to her queer identity.

“I’ll never get the kind of acknowledgment from my parents that I got from her,” Ms. Helms said, her voice cracking with emotion. “I think about her almost every day.”

When their time in Professor Hassold’s classroom ended, many students worked for her as teaching assistants and sought her out for career advice. When they returned to Sarasota later in life, they would make dinner plans with their old mentor.

As Dr. Archer put it, “she had a collection of students in the same way that she had endless collections of books.”

Professor Hassold retired in 2016 at 85. In her final years, she told some of her former students that she planned to leave them something when she died. She didn’t have much family apart from a brother and a few nieces. This was not a woman who lived luxuriously — driving a beat-up Toyota Corolla and cycling through a modest wardrobe. The students were touched, but they weren’t expecting much.

“She didn’t have a family, but we were her family,” Mr. White said. “She adopted us, and we adopted her.”

Bittersweet Endings

In April 2020, Professor Hassold had a stroke at the grocery store and collapsed.

In July of that year, as she was making some progress in her recovery, a fall on the bathroom floor left her needing hospice care. At the peak of the coronavirus pandemic, cordoned off from the world, Professor Hassold died on July 15, 2020. She was 89.

Her former students held a virtual memorial service, crying and laughing over Zoom as they shared stories. Many joked that they had secretly hoped she would die in the classroom, her happy place. But they took solace that she died before New College became unrecognizable.

In the years after her death, Gov. Ron DeSantis of Florida set his sights on transforming the school into a bastion of conservative values. The school shuttered its gender studies program and began recruiting students from Christian schools. Professor Hassold’s students were sure she would be appalled by how it changed.

In August 2021, Professor Hassold’s former students received a package of legal documents that revealed her biggest secret. She had amassed a $2.8 million estate and was dividing it among the 36 people closest to her — 31 of whom were former students, according to documents shared by Steve Prenner, the executor of her estate and a former student.

Some of the students were shocked, particularly those who could not recall when they had last spoken to her.

Professor Hassold had allotted the money based on how close she had been to each student, and how much she believed they needed the money, according to the former students. The payments ranged from around $26,000 to $560,000.

Ms. Helms used part of the roughly $26,000 that she received to help her recover from surgery. Other former students used the money for a down payment on a house, to travel or simply to pay down debts and cover their bills.

It suddenly made sense, Ryan White thought as he opened his letter, why she worked until she was 85, lived so frugally and hid away at times. It was partly the post-Depression era in which she was raised, as well as her fierce independence. But perhaps she had been saving up with her students in mind all along.

“She wanted to give as much away as she could,” said Mr. White, who also received around $26,000.

After Dr. Archer opened her letter, she stepped out into the Manhattan summer and bought a bottle of sherry — a tribute to her Professor Hassold, who loved to drink it.

She thought of what she might do with the $100,000 the letter promised her — open a savings account, maybe buy a home someday, and commit to her career in academia.

For Dr. Archer, the money felt like a message from her mentor:

“Here’s a little something to help you be you.”

Of all the contenders to be the next pope, Danny Kind might not be an obvious choice. His shaggy hair is tinted green, and the other day he was wearing a Korn T-shirt under his ceremonial robes.

“I’m an Ashkenazi Jew from Orlando, so I’m not very Catholic,” he said. There’s also that.

None of this is disqualifying in a class at the University of Chicago called “The Italian Renaissance: Dante, Machiavelli, and the Wars of Popes and Kings,” better known by students as “pope class” or “pope LARP” (as in live-action role play). The centerpiece of the class is a simulation of the conclave of 1492, an historical gathering rife with accusations of scandal and corruption.

This is the 15th year since Prof. Ada Palmer began running the simulation, but the first time that it has been interrupted by the death of an actual pope. Pope Francis died on April 21, the same day that the students were set to vote in their own conclave.

The class arrived that day at Rockefeller Chapel, a Gothic Revival structure on campus that stands in for the Sistine Chapel, with a surreal sense of the weight of their decision.

“I’m a Catholic so it kind of sucked for me, but there was a lot of excitement,” said Joseph DePaula, 21, a third-year student who took the class two years ago and returned this year as a volunteer.

When Mr. Kind from Orlando — Cardinal Ascanio Sforza in the simulation — was elected on the fifth ballot, volunteers waved white flags from a balcony, symbolizing the smoke that billows from the Sistine Chapel when the cardinals have chosen a new pope.

Dr. Palmer, a historian and novelist, compared the class to the history version of a language immersion class. And the approach does more than help students recall names and dates. It is also a lesson in “plural power,” where anyone can change the course of history.

In the simulation, “everybody has power but nobody has control,” Dr. Palmer said. “Even the most powerful people don’t actually manage to control things enough to get the outcome they want, and even the least powerful people, when they work at it, can affect and influence what happens in the end.”

By last week, the final stretch of the simulation, some students had a hard time differentiating their real lives from their 15th-century identities.

Elsa Cukierman, who portrayed the nobleman Franceschetto Cybo, said she once accidentally called her real-life boyfriend by the name of her character’s wife. Others frantically responded to reports of a rival’s treachery on their phones at a nightclub at 3 a.m.

“Don’t eat, don’t speak, just pope,” said Julia Morales, who painted her nails baby blue to match the dress she wore as Lucrezia Borgia, the illegitimate daughter of the real Pope Alexander VI. (Events evolved differently in this year’s simulation.)

“We’re great friends in real life,” chimed in Emily Curran, dressed in the red robes of Cardinal Ardicino della Porta Jr., who opposed the Borgia family’s aspirations. “We just haven’t been able to hang out because we can’t talk about anything else but pope class.”

On April 30, the final day of the simulation, the students arrived in a bustle of excitement. They rifled through the racks of clothing that Dr. Palmer has procured over the years from sources like Renaissance fairs and the BBC’s costume department. She has alerts on Etsy and eBay for the phrase “used Shakespeare costume.”

The pope opened the proceedings with a moment of silence. At one point he assented to a petition to give an Italian cardinal control over a town in Bologna with an enthusiastic “hell, yeah!”

A duel broke out between Michael Tarchaniota Marullus and Pandolfo IV Malatesta. Then the pope himself threw off his robes to initiate his own duel with Cesare Borgia. (Borgia immediately surrendered, to the pope’s apparent disappointment.)

In real life, the 1492 conclave ended with the selection of Rodrigo Borgia as Pope Alexander VI, an outcome so heavily influenced by bribery that it inspired new rules against simony, or the selling of church offices.

But the class is a simulation, not a re-enactment, Dr. Palmer explained. That means that while students portray (mostly) real-life historical figures, they are set loose to make their own decisions.

Thus the 2025 election of Ascanio Sforza, a figure who did exist, as Pope Ambrose, who did not.

The recent success of the movie “Conclave” added to the feeling that the simulation was relevant to the real world this year. One group went to the theater in cardinal costumes, on loan from Dr. Palmer. As for the real conclave in Rome this week, Mr. Kind and several others said they were rooting for Cardinal Luis Antonio Gokim Tagle, a contender from the Philippines who is often called the “Asian Francis.”

At the end of the final simulation, students bought art and made hasty marriage arrangements, rushing to fulfill as many of their characters’ objectives as possible. Then they took off their costumes and made their way to a classroom, where they debriefed and revealed various schemes and misunderstandings.

Cesare Borgia arrived toting a skateboard. Mr. Kind opened up his laptop and put on a playlist including Joy Division and Modest Mouse. A cluster of gods and angels snacked on Oreos.

For Mr. Kind, his election as Pope Ambrose was the culmination of years of dreaming. He heard about the class from a high-school history teacher, and wrote his admissions essay to the university about his desire to participate. Right before the vote, he kissed his grandfather’s small silver mezuza, which he wears around his neck.

Mr. Kind is not the first Jewish pope, Dr. Palmer said. There have also been two Muslim popes and a transgender Catholic pope.

Mr. Kind broke down in tears when he removed his red cardinal vestments to don the white and gold robes of the Vicar of Christ. The experience was almost intoxicating. “Last Monday I got to excommunicate a guy,” he recounted. And given the circumstances swirling outside campus, it was hard not to muse about the possibility of real power.

“As far as I know, I’m the only person in the world claiming to be the pope right now,” Mr. Kind said. “I think that technically makes me pope.”
