North Texans on Monday will begin celebrating the life of former Dallas Congresswoman Eddie Bernice Johnson, including a wake and prayer service at Concord Church that President Joe Biden plans to attend.

Johnson’s body will lie in state at Fair Park’s Hall of State from 10 a.m. to 3 p.m., followed by a procession to Dallas’ Concord Church for the wake and prayer service from 6:30 p.m. to 8 p.m. Johnson’s funeral is scheduled for Tuesday, 10 a.m. at Concord. On Wednesday she’ll be buried in Austin at Texas State Cemetery.

Numerous dignitaries are expected to attend the services memorializing Johnson.

A trailblazing public servant and the first registered nurse elected to Congress, Johnson died December 31 due to a post-surgery infection.

Before serving in public office, Johnson was a civil rights activist with a thriving nursing career. She was the first Black person to serve as chief psychiatric nurse at Dallas’ VA hospital.

Her 50-year career in electoral politics included stints in the Texas House and Senate, where she broke barriers often faced by women and minorities. Johnson was the first Black person to serve in the Texas Senate since Reconstruction.

Elected to the Dallas-anchored District 30 in 1992, Johnson focused much of her attention on delivering resources to North Texas, particularly for transportation, infrastructure and flood control projects. She promoted science, technology, engineering and math education and shepherded major funding for science and technology, including NASA. Johnson was instrumental in securing tens of billions of dollars to revive the U.S. semiconductor chip industry.

The once-segregated Union Station in downtown Dallas bears her name, as does the Eddie Bernice Johnson Stem Academy in Wilmer.

“She gave Dallas all she had,” said her son, Kirk Johnson.

The circumstances behind Johnson’s death are controversial.

Her family intends to bring a lawsuit against Baylor Scott & White Health System, alleging negligent care at the hospital’s rehabilitation center led to her death. After back surgery, Johnson was sent to Baylor Scott & White Institute for Rehabilitation. In September Kirk Johnson said he found his mother alone and in pain. A news release announcing the family’s intention to bring a lawsuit states she was “lying in her own feces and urine,” which they contend led to the lumbar spine infection that killed her.

In a statement last week Baylor Scott & White said: “We are committed to working directly with the Congresswoman’s family members and their counsel. Out of respect for patient privacy, we must limit our comments.”
