Kaiser graduated from the Temple University’s Tyler School of Art with a degree in painting and printmaking. In 1970 he was one of the first artists hired by the Philadelphia Print Club (now the Print Center) to create prints for their Prints in Progress program. From 1972 to 1983 he worked as a public artist in Philadelphia Museum of Art’s Department of Urban Outreach (later renamed the Department of Community Programs). In 1972, Kaiser became the first Artist-in-Residence at the Samuel S. Fleisher Art Memorial. From the mid-1980’s until his retirement in 2008, he worked in the installations department at the Philadelphia Museum of Art, hanging exhibitions and installing art. He exhibited continuously since 1972, with his work appearing in many solo and group exhibitions.
