Thomas Lauritsen--or Tommy, as he was always called--was the son of Charles Christian Lauritsen, one of Caltech's most prominent nuclear physicists. Tommy Lauritsen's forty-one year association with Caltech began in 1932 when he entered the Institute to pursue his undergraduate degree. Following the award of his PhD in 1939, he left Caltech for postdoctoral study at what is now the Niels Bohr Institute in Copenhagen. He returned to Caltech in 1941 and was appointed to the physics faculty in 1946. He served Caltech continuously until his untimely death from cancer at the age of fifty-seven in October, 1973.
