Oct. 21, 2005 — -- For more than 25 years, David Schroer was a star in the U.S. Army, rising through the ranks to become a Special Forces Commander while leading a classified anti-terrorism unit involved in covert operations. Fellow soldiers described him as a classic military man.
That all changed two years ago when he abruptly retired from the military and made a shocking announcement that stunned his colleagues and family alike. He would no longer be Col. David Schroer, because he is now Diane Schroer, a transsexual.
In her first television interview, Schroer explains to "20/20" correspondent Deborah Roberts why, after decades of service in one of the most dangerous and macho lines of work, she became a woman.
"Does seem a bit of a disconnect," Schroer acknowledges. But, she says, she has struggled with her gender identity -- privately -- since childhood.
"Something was different since even before I can remember. I was always enthralled with things the girls were doing. ... Whenever my parents were gone, I would experiment with my mother's makeup. And wondered why I enjoyed doing that... Wondered why I couldn't carry a purse," Schroer tells Roberts.
Schroer's family has come to accept her decision, but she is now embroiled in a gender discrimination lawsuit against the Library of Congress, which, she claims, withdrew its offer of employment based on her sex.
Her lawsuit may be precedent-setting, but Dr. George Brown, a military psychiatrist, said Schroer's story is not unique. He said he's treated hundreds of soldiers who are transsexuals. Brown described transsexualism as "a sense that there's been a biological mistake -- that the body doesn't match who you are as a person inside."
Schroer says it was apparent to her from the time she was a child, growing up in Oak Lawn, Ill., just outside Chicago. Her brothers, Gary and Bill, only remember a happy childhood with their little brother, however.
"I think it was probably very much...the typical American family, three boys growing up. We played baseball. We played in the neighborhood. We rode bikes. We pretty much did what other kids did in the '50s," said Bill Schroer.
Schroer's siblings never knew their little brother was suffering quietly, never daring to mention the anguish inside.
Schroer says growing up as a boy left her feeling uneasy and deeply conflicted about who she really was. "When I hit adolescence, it was at times consuming. ... So I did everything I could to push that out of my mind," she tells Roberts.
When David Schroer entered Northern Illinois University, he was in full denial of his gender crisis. He worked as an auto mechanic, an electrician and joined ROTC. After graduation, he entered Special Forces and somehow thrived in the most dangerous of military careers. He even fell in love with a woman and got married.
"We had a normal sexual relationship," Schroer tells Roberts. "Although I would say that I would often think of myself being on the other side of the relationship."
Schroer managed to keep up the act, rising through the ranks of the military. By his mid-40s, he was a Special Forces commander leading a classified anti-terrorism unit and managing an $8 billion budget. He even briefed Vice Dick President Cheney on secret missions.
Then, two years ago, he grew tired of denying what he believed was his true sexual identity.
"I think when I learned enough to understand what it was that I was really feeling ... I could either hide that, or I could acknowledge to the world that I was in fact a woman. And receive their acknowledgement back," Schroer says.
Schroer told his wife first, even hoping there might be a possibility they could stay together. But the couple decided to separate.
Schroer's marriage was over, but he was finding fulfillment for the first time. He began openly dressing as a woman and calling himself Diane. Schroer was retired at the time, and didn't have to break the news to Washington's top brass. But Schroer did begin telling his Special Forces buddies, including retired Lt. Colonel Dan Bernard.
"The way she explained it to me was by showing me some photos that had been taken of her as a woman in a business kind of setting, wearing makeup and with a big wig and women's clothes. ... And I didn't get mad and I didn't storm out," Bernard said.
"I explained to him about being transgendered and what that meant, and he sat back for a moment and said, 'You really had me scared. Wow, I thought you were going to tell me something bad.' ... It was a tremendous relief," Schroer recalls.
Now Schroer was confident enough to tell family, nervously breaking the news to Bill and Gary -- still dressed as David.
Even though the news was, and continues to be, difficult to accept, Gary Schroer said there was never a question in his mind about being supportive to his younger brother. "It's still tough. But support and acceptance are two different things," he said.
Schroer then began the long and painful process of becoming a woman, undergoing intense therapy and taking female hormones under medical supervision. He also started wearing makeup, and underwent extensive cosmetic surgery.
In 12 hours of surgery, Schroer said, doctors gave him "a scalp advance, a forehead revision, nose reconstruction, upper lip revision, jaw and chin reshaping, and a tracheal shave." In a tracheal shave, the surgeon reduces the cartilage in the throat to get rid of a masculine-looking Adam's apple.
The genital reassignment surgery would come later. But in the meantime, Schroer was already looking more feminine and beginning to envision a new relationship.
But Schroer wasn't envisioning a sexual relationship with any men. Schroer is interested in dating women. "I would say I am in fact a lesbian," she said.
Schroer's desire to be with women is not uncommon for transsexuals. Brown says gender identity and sexual preference are two entirely different things.
"If sex and gender were the same, then that would make no sense at all. Sexuality is who you're attracted to. Gender is who you are as a person, male or female. So, the surgery and the transition is all about matching the mind with the body. It has nothing to do with sexuality," Brown said.
While Schroer is grateful to have the acceptance of her family, she has encountered challenges in her public life. While still transitioning to become female, Schroer applied for, and was offered, a job as a terrorism analyst at the Library of Congress late last year.
Because she was still legally David Schroer, she did not reveal her plans to her prospective employer during the interview.
She decided to tell the woman who hired her that she would begin work as a woman, not a man. Schroer said it seemed as though the woman took the information in stride and that the hiring was going forward as planned.
But the following day, Schroer said she was told that she was no longer "a good fit" for the position. Schroer and her brothers were furious.
With her brothers' encouragement, she filed what many say will become a landmark law suit against the Library of Congress, charging gender discrimination.
She says she's protected under Title VII of the 1964 Civil Rights Act. "She is the same exact person that the Library of Congress knew that they wanted when they first encountered the application. And so there's nothing about that that's changed, except her physical appearance," said American Civil Liberties Union attorney Sharon McGowan, who is representing Schroer.
The Library of Congress first agreed to an interview with "20/20," but then declined, citing Diane's lawsuit. In an e-mail, they wrote that they "acted appropriately and complied with the law" and that "claims such as those raised by Ms. Schroer ... are not covered under Title VII of the Civil Rights Act" or the U.S. Constitution.
While waiting for her day in court and looking for a full-time job, Schroer's deepest fears concerned her family who had yet to see her as a woman. In July, Schroer allowed "20/20" cameras to film her first visit as a sister with her family in suburban Chicago.
The family was understandably surprised by the dramatic change in her appearance, but before long the brothers were reminiscing about their childhood. For Gary and Bill Schroer, the memories are bittersweet as they feel in a sense they've lost a brother while gaining a new sister.
For Schroer, the childhood memories have a far different meaning. She's always known that inside that little boy lived a little girl who longed to grow up and become a woman. "What's great about my life now is that it's unified, it's focused and this huge distraction that was in my life is now gone."
