Joseph Rantz

Joseph Harry Rantz (March 31, 1914 – September 10, 2007) was an American rower and chemical engineer. He won the Olympic gold in the men's eight at the 1936 Summer Olympics. Rantz worked as a chemical engineer for the Boeing aviation company for 35 years. He pioneered a dust-free particle workspace concept known as "safe room" that had wide impact on improving work environments in both aerospace and medical facilities. It was a precursor to the cleanroom.

Early life Born in Spokane, Washington, Joe Rantz had a harsh childhood in Boulder City, Idaho and, later, Sequim, Washington. His mother, Nellie Maxwell (1881–1918), died from throat cancer when Rantz was four. Rantz is the central character in the non-fiction book The Boys in the Boat, which chronicles his struggles through life in his early years, culminating with his Olympic gold medal win from the seven seat of the US men's eight at Berlin in 1936. The book inspired the PBS documentary American Experience: The Boys of '36 and a 2023 feature film directed by George Clooney, where Rantz was portrayed by Callum Turner.

Rantz earned a chemical engineering degree from the university and worked for Boeing for 35 years following his retirement from rowing, inventing a precursor of the cleanroom known as "safe room".

Rantz died of congestive heart failure at the home of his daughter in Redmond, Washington, at age 93.
