Hyman Isaac Feldman
Hyman Isaac Feldman (1896 - 1981) was a Yale-educated architect who started his life in Poland during 1896, and ended it with his career in New York in 1981. He has always had a modest way about his work, designing hundreds, or maybe even thousands (according to his daughter) of buildings within his life-time.
He remained out of the media, and didn't leave a paper trail for one to follow after his death. His last remaining daughter, searched diligently for his history by researching his hometown library and contacting architects he had known.
Feldman attended Yale in the 1920s after having to postpone his studies due to World War I. Previous to that, he attended Cornell university and studied landscape architecture. In the 1950s, he supported the newly established Yale School of Architecture with scholarship funding for meritorious students. He also donated many rare books to the library.
Unlike many architects, Feldman didn't have an emotional attachment to his buildings. If one was destroyed, it didn't make a difference to him. His idea of success was not to creating ever-lasting buildings, but it was to support his wife and children.
His designs are not artistic. They simply serve the purpose they were intended to and he didn't waste time with all the bells and whistles. Even though this was criticized by architects such as Philip Birnbaum, he was still awarded contracts because he knew how to design buildings that minimized construction costs and were practical - one of his methods being rounded corners on doors and entry ways so it was easier to move furniture. His Park Lane Tower, was criticized:
“Despite its bucolic name, this rust-colored high-rise from 1965 has all the bucolic charm of a World War II artillery turret. Its only distinction is that it is the building inhabited by the Jeffersons in the 1970s sitcom of that name.” 
Today, his remaining buildings are known as retro, which seems to be in style. The funny thing, is that building styles work just like fashion styles. Anything that is outdated now, will come back into style eventually. At the time of designing his buildings, he was considered to be outdated and his post-war buildings were described as bland.
His most well known work is 1025 Fifth Ave. However, he has nothing to do with the current entrance it is today. His idea was to create a snaking entrance hallway so that all residence on that corner lot could say they have a Fifth Avenue address. 
After his death, the University of Wyoming wrote to his children asking for information or documents about Feldmans personal life so that they could archive it. This came as a surprise to the family considering Feldman had never been near Wyoming. Yale had sent a condolence letter to the family, but didn't inquire about any information.
Unfortunately, Feldman did not leave a very colorful paper trail behind. All that could be found regarding his professional career were a few undated renderings, and a few photographs.
