His father was an immigrant from Germany who made a fortune after gaining control of the American Metal Company (founded by Berthold Hochschild and Jacob Langeloth). Jacob Longeloth was his father's mentor hence his son's middle name. His mother was the daughter of Alabama banker, Alfred Huger Moses. He had three siblings: Carl M. Loeb Jr., Henry A. Loeb and Margaret Loeb Kempner (married to Alan H. Kempner). Loeb attended Dartmouth College and then transferred to Harvard College where he graduated in 1924.
