Biography

Irwin I. Shapiro is recognized among Jewish contributors to Science & Medicine — Astrophysicist who discovered the Shapiro time delay and pioneered radar astronomy of the planets

How & why

Irwin I. Shapiro is an astrophysicist who in 1964 predicted the Shapiro time delay — the slowing of light as it passes near a massive body — one of the classic tests of general relativity, which he later confirmed by bouncing radar off Venus and Mercury, pioneering planetary radar astronomy. A longtime Harvard professor, he directed the Harvard-Smithsonian Center for Astrophysics. He is listed among Jewish scientists by the Jinfo compilation.
