Oral History of Allen Baum

Elmer's son and old friend of Steve Jobs and Steve Wozniak.

In 1976, Elmer Baum loaned $5000 to Steve Jobs and Steve Wozniak, who were friends of his son Allen, so that they could build the Apple I computer. Elmer noted that they "paid it back fairly quickly"; Jobs said that without the loan, "we wouldn't have made it." Elmer was hired as employee #34 of the newly incorporated Apple Computer in 1978.[1][4] His sons Allen and Peter also joined Apple.[3]


Elmer Baum passed away due to kidney failure in 1993.[2] He was interred with his late wife Charlotte at Los Gatos Memorial Park in San Jose, California.[5]
