Born in Philadelphia, Pennsylvania on May 10, 1912, Irv Kosloff was a son of Russian Jewish immigrants Lillian and Louis Kosloff. He had two brothers, Carl and Charles Kosloff. Irv Kosloff graduated from
South Philadelphia High School in 1930, where he played football and basketball as an offensive center and middle linebacker. Initially, he set out to be a dentist; however, he sustained a knee injury, and lost his athletic scholarship to
Temple University, which he had attended for approximately two years. Forced to drop out and search for a job due to financial problems, he found work in the traffic department of the Container Corporation of America in
Manayunk, Philadelphia. In 1932, he founded the Roosevelt Paper Company, which was located on State Road near Cottman Avenue in Philadelphia. Over the years, the company grew into one of the nation's leading merchant/converters of printing and packaging paper. ==Career==
