Which actor's real name was Eugene Maurice Orowitz?

Player #252573, my friend and I got to see him on the set of bonanza at universal studios in 1966 he waved at our tram going by

Michael Landon has a genuine memorable laugh. I got to see him and the rest of the cast in 1960 when they were in Akron Ohio hosting the annual Soap Box Derby. It was a thing that the hosts of the Derby tour the Akron City Children’s Hospital where I had been admitted for a serious operation. They all came. Two years later when I was in again for the same operation again F Troup toured. Larry Storch did not come. Ken Bailey was very kind. He saw my empty bed (I was being operated on) and talked to my mother for a long time. She told me later that his people tried to hurry him along but he told them he wanted to talk to my mom. It was an eye operation and was very serious. Mom was very worried.

miss you little Joe!
