Red Seidelson

College career After Seidelson graduated from Schenley, he was watching the football team play a year later and "anyone could see he would have liked to get in and join them". He was noticed by Andrew Kerr, a math professor at Schenley as well as the freshman football coach for the Pittsburgh Panthers of the University of Pittsburgh. When he first joined the Panthers, Seidelson was put at quarterback, but head coach Pop Warner switched him to guard after noticing his "vicious blocks".

Standing at and weighing for the Panthers, Seidelson was described in the Pittsburgh Post-Gazette as not "so big, as guards go. But it's enough. It represents about as well-rounded physical development as there is on the squad, a fine combination of sheer power with agility". Seidelson succeeded Sack as Pittsburgh's leading guard in 1923 and was considered one of the best at his position on the East coast. He was honored with a gold football by the Panthers following the season. In 1925, he began the season with the Toronto Tigers in Ohio before joining the Frankford Yellow Jackets of the National Football League (NFL). He replaced Jim Welsh as starting guard for the Yellow Jackets and also saw playing time at tackle. Seidelson became the NFL's first Romanian-born player. He appeared in nine NFL games, seven as a starter, during the 1925 season, as the Yellow Jackets placed sixth in the league with a record of 13–7. He also worked for the Head Start program. With his wife, Freda, he had a daughter and a son. He died in Pittsburgh on July 4, 1986, of heart failure, aged 84.
