Abraham Wald (/wɔːld/; German: [valt]; Hungarian: Wald Ábrahám, Yiddish: אברהם וואַלד; 31 October 1902 – 13 December 1950) was a Hungarian and American mathematician and statistician who contributed to decision theory, geometry and econometrics, and founded the field of sequential analysis. One of his well-known statistical works was written during World War II on how to minimize the damage to bomber aircraft and took into account the survivorship bias in his calculations. He spent his research career at Columbia University. He was the grandson of Rabbi Moshe Shmuel Glasner.
