Abraham Wald (/wɔːld/; Hungarian: Wald Ábrahám, Yiddish: אברהם וואַלד; 31 October 1902 – 13 December 1950) was a Jewish Hungarian mathematician who contributed to decision theory,[1] geometry and econometrics, and founded the field of sequential analysis.[2] 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.[3] He spent his research career at Columbia University. He was the grandson of Rabbi Moshe Shmuel Glasner.
