Rosenbaum's initial interest in art glass led him to enroll in courses at Virginia Commonwealth University specifically for glass blowing and casting.[1]
One of his first major sculptures, a 6-foot-tall (1.8 m) piece which he called Shoah, was constructed of wrought iron meant to remind the viewer of concentration camp gates, glass intended to recall Kristallnacht, a rotating "searchlight," rocks and wood.[1] Rosenbaum’s Shoah is now on permanent display at the Virginia Holocaust Museum.[1] In an interview, Rosembaum said that he had seen a wide range of reactions to this specific sculpture, "from the little ones trying to climb inside to the tears of the elderly."[1]
Rosenbaum produced his first one-man art show at the Valentine Museum in 1997.[1] His work had received awards from art shows as far from Virginia as Pennsylvania and Michigan.[1]
Al Rosenbaum died on April 11, 2009, at the age of 82. He was a resident of Richmond, Virginia, at the time. He was buried in Forest Lawn Cemetery.[1]
