I met Jerry in 1970 for the first time, when I came as a post-doctoral research associate to NASA Ames Research Centre where I worked for 2 years in the same branch as Jerry. During this period I met also often Gracia, his wife, on the occasion of many private coming together of colleagues with relatives. Later on, because of our sympathy, we met several times again in Germany, my home country. The joined related picture was taken in Seligenstadt on July 24, 1992, with Jerry, his wife Gracia, Mr. Lemke (I guess, left) with children, and myself (middle).
I'm glad that my kind former colleague and dear friend up to these days could enjoy such a long interesting life in midden of his large caring family.
