Note
Inception and Purpose:
The WEIZAC project began at the Weizmann Institute of Science during 1954–1955. It was based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann. The driving force behind WEIZAC was Prof. Chaim L. Pekeris, who envisioned it as a means to solve Laplace’s tidal equations for Earth’s oceans and benefit the entire Israeli scientific community, including the Defense Ministry.
Building WEIZAC:
The project faced challenges, including skepticism from some Israeli scientists who deemed building a computer in Israel as impractical. Gerald Estrin, a research engineer from the von Neumann project, led the effort. He arrived in Israel with his wife, Thelma, who was also involved in the project. The team had schematics but no parts, and their execution plan was somewhat improvised.
Recruiting Skilled Staff:
An advertisement was posted to recruit staff for the project.
Many applicants lacked formal education records due to the Holocaust or immigration, but Israel’s tight-knit technical community allowed them to connect. WEIZAC provided an opportunity for mathematicians and engineers to contribute to Israel’s scientific progress.
Impact and Recognition:
WEIZAC became operational and significantly advanced science and technology in Israel. In 2006, the IEEE recognized WEIZAC as a milestone in electrical engineering and computing, awarding the team the prestigious WEIZAC Medal.
In summary, WEIZAC’s journey exemplifies determination, innovation, and the pivotal role it played in shaping Israel’s scientific landscape
