Roald Hoffmann

Roald Hoffmann is a Polish-born American theoretical chemist, educator, poet, and playwright renowned for his pioneering work in applying quantum mechanics to predict the course of chemical reactions.

Born Roald Safran on July 18, 1937, in Złoczów, Poland (now Zolochiv, Ukraine), to a Jewish family—his father Hillel Safran, a civil engineer, and mother Clara Rosen—he survived the Holocaust after his father was executed by the Nazis in 1943, hiding with his mother until liberation in 1944.

Roald Hoffmann was born Roald Safran on July 18, 1937, in Złoczów (now Zolochiv, Ukraine), then part of Poland, into a Jewish family. The town, a regional administrative center with a pre-war population of about 12,000, of which roughly half were Jewish, was located in eastern Galicia. His parents named him after the Norwegian explorer Roald Amundsen, reflecting a sense of adventure amid the family's cultured background.

His father, Hillel Safran, was a civil engineer educated at the Lviv Polytechnic Institute, where he managed a local quarry, fostering an environment of practical technical knowledge. Hoffmann's mother, Clara (née Rosen), born on March 24, 1914, in Złoczów, was a teacher trained in bookkeeping and worked at the local high school; she came from a family rooted in the region, as the daughter of Wolf Rosen and Fanny Wolfish. This parental emphasis on engineering and education surrounded young Hoffmann with intellectual stimulation in a close-knit Jewish community.

The German occupation of Złoczów in July 1941 rapidly escalated persecution against the Jewish population there, where Roald Hoffmann's family lived. Hoffmann's grandfather and several relatives were murdered shortly after the occupation, and his father, Hillel Safran, was conscripted into forced labor at a nearby camp, enduring harsh conditions while attempting to protect his family from deportation.
