Richard Plotz — Mailing List Manager
Dick Plotz has been fascinated by genealogy since seeing a family tree at his grandmother's cousins' club in 1963 and meeting an actual third cousin. He has expanded his own and his wife's family trees in all directions, and estimates that they now include about 20,000 names; he has met many of these cousins. He particularly appreciates being able to tell people that his wife is related to Hedy Lamarr.
In real life he is a pathologist. This means that he sits at a microscope and looks at slides; it's been more than 20 years since he performed an autopsy. Pathology and genealogy are related in that they both involve solving puzzles... and Dick's other consuming avocation is, what else? Solving puzzles. He is active in the National Puzzlers' League, where he goes by the nom de plume "Geneal", and is the proud recipient of a trophy as best rookie from Will Shortz's crossword mini-competition held each year in Pleasantville.
Lance Ackerfeld — Manager, JewishGen Yizkor Book Project
Lance's first contact with JewishGen was in 1997, when he began by using the site to search for clues to his family’s past in Poland. That year he responded to a request to find a friend in the Israeli phone book. As a result of that email, he began assisting the JewishGen Yizkor Book Project as a Permissions Coordinator in finding landsmanshaftn in Israel, and explaining to them why it was important to place the translations of this precious material on the Internet.
With a background in computing – his day job being in software development and database programming – he has coordinated the Yizkor Book Project's web pages since 1999, managing a small but highly dedicated and talented team of HTML'ers.
In 2009, the opportunity arose to take on the position of Yizkor Book Project Manager, Lance saw this as a chance to assist with his gained experience and contacts in keeping this important project going forward.
Lance was born in Australia and now lives with his family in a kibbutz in the north of Israel.
