NEW YORK -- Apple CEO Tim Cook says he's proud to be gay.
The public declaration, in an essay written for Bloomberg Businessweek, makes Cook the highest-profile business CEO to come out as gay.
Cook said that while he never denied his sexuality, he never publicly acknowledged it, either. The executive said that for years he's been open with many people about his sexual orientation and that plenty of his Apple colleagues know he is gay.
Cook wrote in the column, published Thursday, that it wasn't an easy choice to publicly disclose that he is gay, but that he felt the acknowledgement could help others.
I consider being gay among the greatest gifts God has given me.
Three days ago, Cook challenged his home state of Alabama to better ensure the rights of the lesbian, gay, bisexual and transgender community.
Alabama is among the states that do not recognize same-sex marriage, and it also doesn't offer legal protections on the basis of sexual orientation or gender identity. Cook is a native of Robertsdale, Alabama, and attended Auburn University.
The announcement is a "huge deal," said Richard Metheny of executive search firm Witt/Kieffer.
"This really sets the stage for 'It's OK,' " he said. "Anything CEOs do is very magnified, very complicated, and it affects a lot of people. There's no taking away that he has become a role model and will have a positive influence on lots of people that would like to be comfortable being out in the world of business."
"I consider being gay among the greatest gifts God has given me," Cook wrote in the essay Thursday.
The executive said that "being gay has given me a deeper understanding of what it means to be in the minority and provided a window into the challenges that people in other minority groups deal with every day."
'Inclusion Inspires Innovation'
Cook said he's been lucky to work for a company that "loves creativity and innovation and knows it can only flourish when you embrace people's differences."
Cook, 53, succeeded Apple founder Steve Jobs as CEO of Apple (AAPL) in 2011.
Apple has been an outspoken champion for diversity since Cook succeeded Jobs as CEO. The company has trumpeted the phrase, "Inclusion inspires innovation," as a rallying cry. Cook has reinforced that message on his Twitter account with periodic posts supporting gay rights in the workplace.
Cook's public declaration that he is gay comes a little more than two months after Robert Hanson -- the former CEO of American Eagle Outfitters (AEO) -- wrote a piece for Time in which he talked about being an openly gay man for as long as he's been in business and running companies.
Hanson is currently the CEO of luxury jewelry brand John Hardy.
There are no other publicly gay CEOs of major companies. United Therapeutics (UTHR) CEO Martine Rothblatt, who was born male and is now female, has been open about her transgender status.
