CONCORD, N.H. – New Hampshire inventor and businessman Dean Kamen resigned from the board of BETA Technologies this week, after documents were released in late January showing his longstanding ties to Jeffrey Epstein.
While Kamen has previously downplayed his relationship to Epstein, the latest disclosure from the US Department of Justice showed that he had visited the disgraced financier’s Caribbean island in 2013, and that the two had remained in contact for years after Epstein was first convicted of sex crimes involving a minor in 2008.
Kamen voluntarily stepped down from BETA’s board of directors on Wednesday “to avoid potential distractions as the Company remains focused on executing its strategic priorities,” according to a Thursday company filing with the US Securities and Exchange Commission.
Kamen, perhaps best known for inventing the Segway in 2001, has not been accused of any wrongdoing related to his relationship with Epstein.
BETA, an electric aircraft company headquartered in South Burlington, Vt., first announced that Kamen had been placed on a voluntary, indefinite leave of absence on Feb. 4. The board of directors said it had launched an independent investigation into the matter, according to a company statement.
A spokesperson for the company declined to answer questions about the status of that investigation on Friday, and said the company would not comment on the matter beyond its filing.
Some of the other organizations Kamen is affiliated with have previously announced they would review his ties to Epstein.
That includes the nonprofit Kamen founded, Advanced Regenerative Manufacturing Institute (ARMI) in Manchester, N.H., whose board of directors said Kamen had recused himself from the board pending an independent review in early February.
The youth robotics educational nonprofit he founded, FIRST, also said Kamen would take a leave of absence while an outside law firm conducts an independent review.
A spokesperson for the XPRIZE Foundation, which partners with FIRST, said Kamen is no longer part of an advisory group as of Feb. 5, in light of his leave of absence.
And Sequel Med Tech in Manchester, N.H., a company co-founded by Kamen, announced an independent review in early February.
A spokesperson for Kamen’s company DEKA Research & Development Corp. has not responded to questions about whether it will take similar action.
The latest tranche of US DOJ documents was not the first time Kamen had been linked to Epstein.
Two undated photos were released in December 2025 showing Kamen socializing with Epstein in a tropical location, and sharing a Segway with Epstein accomplice Ghislaine Maxwell at a convention center. Kamen said he had “only limited interactions” with Epstein and “no specific memory” of interacting with Maxwell.
The public has known for years about the flight Kamen took with Epstein in 2003, and about his subsequent ties to Nadia Marcinko, a close Epstein associate who was granted immunity in a plea deal Epstein struck in 2008 with federal prosecutors.
The latest release of documents includes emails the two men exchanged through 2015, and it shows how they traded professional favors and planned travel together.
Kamen has said he has no knowledge of Epstein’s “horrific” crimes and that he regrets the “limited interactions” he had with him.

A court hearing for Cher’s son Wednesday over allegations he broke into a New Hampshire home this month has been canceled.
Elijah Allman’s arrest on March 1 was his second in New Hampshire in a matter of days. Allman, the 49-year-old son of the iconic singer and actress, was also detained Feb. 27, accused of acting belligerently at a prestigious prep school in Concord.

It is unclear if Allman, of Malibu, California, has any connection to the home in Windham, New Hampshire. He is being held in the Rockingham County Department of Corrections, Superintendent Jonathan Banville said.
The hearing Wednesday was continued until an undetermined date after Allman got an attorney Wednesday morning. The attorney, Sarah Landres, did not respond to a request for comment.
Allman, whose father was the late singer Gregg Allman, is charged with two counts of criminal mischief, one count of burglary and a count of breach of bail for breaking into the home on March 1. Police said in a report that Allman did not have permission to be at the home and forcibly entered it.
Officials at St. Paul’s School said Allman last month identified himself as the parent of a prospective student and slipped into the dining hall as some students were leaving the building. Police responded to reports that he was disturbing people in the building.
He was charged with four misdemeanors in the school incident: two counts of simple assault, criminal trespass and criminal threatening. Allman was also charged with a violation of disorderly conduct, which is illegal in the state but not considered a crime. He was released on bail.
Allman did not respond to an email requesting comment, and a phone number for him was not working.
In December 2023, Cher filed a petition to become a temporary conservator overseeing her son’s money, saying Allman’s struggles with his mental health and addiction have left him unable to manage his assets and potentially put his life in danger.
The petition says the superstar performer’s son is entitled to regular payments from a trust fund. But “given his ongoing mental health and substance abuse issues,” she is “concerned that any funds distributed to Elijah will be immediately spent on drugs, leaving Elijah with no assets to provide for himself and putting Elijah’s life at risk,” the petition says.
Los Angeles Superior Court Judge Jessica Uzcategui denied the request, saying she was not convinced that a conservatorship was urgently needed. Allman was in the courtroom with his attorneys, who acknowledged his previous struggles but argued that he was in a good place, was attending meetings, getting treatment and reconciling with his estranged wife.

The son of Cher is scheduled to be in court Wednesday for a hearing over allegations he broke into a New Hampshire home earlier this month.
It was the second arrest in a matter of days for Elijah Allman, 49, of Malibu, California, who was detained Feb. 27 after allegedly acting belligerently at a prestigious prep school in New Hampshire. It was unclear if Allman had any connection to either St. Paul’s School or the home in Windham, New Hampshire.
Allman remains in the Rockingham County Department of Corrections in what is called preventive detention, Superintendent Jonathan Banville said.
Allman, whose father was the late singer Gregg Allman, faces two counts of criminal mischief, one count of burglary and a count of breach of bail for breaking into the home on March 1. Police said in a report that Allman did not have permission to be at the home and forcibly entered it .
In the incident at the prep school, Allman was charged with four misdemeanors: two counts of simple assault, criminal trespass and criminal threatening. Allman was also charged with a violation of disorderly conduct, which is illegal in the state but not considered a crime.
At about 7 p.m. that day, Concord police responded to reports that Allman was disturbing people in the dining hall of St. Paul’s School. After charging Allman, police said he was released on bail as his case works through the court system.
Allman did not respond to an email requesting comment, and a phone number for him was not working. It was unclear from the court records if Allman has an attorney.
