Gary Mokotoff

Gary Mokotoff (April 26, 1937 – August 31, 2025 ) was an author, lecturer, and Jewish genealogy researcher. Mokotoff was the publisher of AVOTAYNU, the International Review of Jewish Genealogy, and is the former president of the International Association of Jewish Genealogical Societies (IAJGS). He was the creator of the JewishGen's Jewish Genealogical Family Finder and the Jewish Genealogical People Finder. He co-authored the Daitch–Mokotoff Soundex system. Mokotoff is co-author of Where We Once Walked: A Guide to the Jewish Communities Destroyed in the Holocaust.

Early life Mokotoff was born in New York City to parents Sylvia Mokotoff (née Friedberg) and Jack Mokotoff. He grew up on the Lower East Side of Manhattan, spending his teenage years in Queens. His grandparents were Jewish immigrants from Russia-Poland. He is the author of SPS-1, SPS-2 IBM 1401 Symbolic Programming System, coauthor of 1401 Autocoder and participated in the 1401 Fortran II compiler project.

In 1965, Mokotoff was drafted into the U.S. Army and spent his entire two-year career in the data processing department at Fort Dix Army Air Base in Fort Dix, New Jersey. He led the team that installed the first computer at Fort Dix (an IBM 1401). For his efforts, he received a Certificate of Achievement from the Commanding General of the base. When he left the Army, he had achieved the rank of Specialist Fifth Class. In 1967, he returned to IBM.

In 1968, Mokotoff left IBM to form his own software company with partner Stanley F. Smillie. The company catered primarily to the retail industry. In the 1980s, the company, Data Universal Corp, developed a software system called Riva which it installed in early computer systems at such national retail chains as The Children's Place, Linens N Things and Bed, Bath & Beyond.

In 1985, he assisted the American Gathering of Jewish Holocaust Survivors and their Descendants to computerize the National Registry of Jewish Holocaust Survivors. This database is now located at the United States Holocaust Memorial Museum.

Genealogy career

The Forward calls Mokotoff an "all-around makher (Yiddish for mover and shaker) in the Jewish genealogical world." Mokotoff became involved in genealogy in 1979 to prove, successfully, that all persons named Mokotoff/Mokotov/Mokotow have a common ancestor. In 1980, he joined the Jewish Genealogical Society Inc. (New York) and the following year became a member of its board of directors. During his tenure on the board, he used his computer background to develop some of the earliest databases for Jewish genealogy including the Jewish Genealogical Family Finder (now called JewishGen Family Finder), a database used by more than 100,000 Jewish genealogists.

Recognizing that there were many spelling variants of Eastern European Jewish surnames, even though they sounded similar, Mokotoff collaborated with Randy Daitch to create the Daitch–Mokotoff Soundex, system which provides a phonetic alternative to searching databases of names. The book won the 1991 "Best Reference Book Award" of the Association of Jewish Libraries. Since then, Avotaynu has published more than seventy books, five of which have won awards. In 2003, the Association of Jewish Libraries gave Avotaynu Inc. its "Body of Work Award." This award has been given only five times in the past twenty years.

In 1987, at the request of Rabbi Malcolm H. Stern and Sallyann Amdur Sack, Mokotoff founded the International Association of Jewish Genealogical Societies, the international organization of Jewish genealogical societies all over the world.

In 1990, Mokotoff became a member of the board of directors of the Federation of Genealogical Societies (FGS). He served on the board, with some interruption, for fifteen years. In 2002, he served four years on the Board of the Association of Professional Genealogists.

In 2001, Mokotoff created the weekly e-zine of Jewish genealogy, called Nu? What’s New?
