In Philip Gambone’s interview with Massachusetts Congressional Representative Barney Frank, Frank recalls that, shortly after he came out publicly, House Speaker Tip O’Neill said to him, “ ‘Oh, Barney, I’m so sorry. I thought you were going to be the first Jewish Speaker,’ meaning that as an out gay man I couldn’t become Speaker. I could have told him that there had already been two gay Speakers: Joe Martin and Sam Rayburn.”
The office building for Congressional Reps is named after Sam Rayburn. Rayburn, according to Wikipedia, “was a Democratic lawmaker from Bonham, Texas, who served as the Speaker of the U.S. House of Representatives for seventeen years, the longest tenure in U.S. history.”
Joseph Martin was a Massachusetts Republican and served as Speaker in a couple two year periods in the 40s and 50s.
I don’t know where Barney Frank got his information on the personal lives of these two men. But, you know, on this I’ll trust Barney.
