With a liveliness of a man decades younger, Harry Kogan looks at his 100th birthday with cheer and satisfaction. Born March 11, 1916 to poor Russian immigrant parents in the Jewish ghetto of Philadelphia, Harry vividly recalls walking to school shoeless, with no hat or no raincoat. A treat would be his mother handing him ten-cents to go to the theater and enjoy a silent movie. After graduating from high school in 1933, Harry quickly took one of the rare jobs available in a garment manufacturing company where he worked his way into being a skilled and valued fabric cutter-a job that paid $35 a week. Harry was raised with two brothers and lived in Philadelphia for the first 91 years of his life before moving to Las Vegas. One of his brothers learned the refrigeration business while enlisted in the Navy and after the war formed a commercial refrigeration business named Kogan Brothers. Harry is a philosophical and philanthropic man. He was slow to retire and traveled the world, took classes and donated to his favorite causes; among which are the Boys Town Jerusalem and the Jewish Federation of Las Vegas. He sat for this interview to honor his Jewish roots, to share his life experiences and spending the past years in Las Vegas.
