JewishGen


JewishGen is a non-profit organization founded in 1987 as an international electronic resource for Jewish genealogy. In 2003, JewishGen became an affiliate of the Museum of Jewish Heritage - A Living Memorial to the Holocaust in New York City, and is now a division of the Museum of Jewish Heritage. JewishGen provides a free, open-access platform for both amateur and professional genealogists to research Jewish family history and heritage.

History

JewishGen was founded in 1987 by Susan E. King in Houston, Texas, as a Fidonet bulletin board with approximately 150 users interested in Jewish genealogy. To access the bulletin board, users dialed into the connection via telephones. Annual donations of $25 were requested to fund the service.
Around 1989 to 1990, JewishGen moved to the internet as a mailing list and online forum, and was called the Jewish Genealogy Conference. It was loosely managed by founding members and volunteers that included Warren Blatt, Susan E. King, Bernie Kouchel, Gary Mokotoff, Michael Tobias, and others active in the community. JewishGen had a website by 1995.
At the end of 2002, King announced that in 2003 JewishGen became an affiliate of the Museum of Jewish Heritage. In 2005, the International Association of Jewish Genealogical Societies gave King an IAJGS Achievement Award for her work with JewishGen, citing the organization's worldwide impact. In March 2008, King retired, and JewishGen moved their administrative office to the museum's facilities.
In 2008, in a partnership with JewishGen, Ancestry.com took over the data center hosting of the JewishGen computerized assets. The agreement improved the JewishGen website's performance, which had been problematic, and created a licensing agreement with Ancestry.com for database access that created a revenue stream for JewishGen. The partnership increases Ancestry.com's access to and integration of Jewish genealogical resources from JewishGen.
In October 2022, JewishGen and the Museum of Jewish Heritage announced the establishment of the Peter and Mary Kalikow Jewish Genealogy Research Center. Located within the Museum, the Center functions as the physical home of JewishGen and is staffed on rotation by eight professional genealogists with diverse areas of expertise, as well as a full-time director
