Who Names Their Kid Learned Hand?

Every time I read one of his opinions I wonder what the deal is with this guy's name. I always assumed he thought highly of himself and changed his name. But, apparently he was born Billings Learned Hand. I guess I don't blame him for choosing Learned over Billings. He got his names from his Uncle and Grandfather, who were both named Billings Peck Learned. Judge Learned Hand's father was a famous New York appellate lawyer. Hand suffered from night terrors throughout his childhood and later admitted that he was a very insecure person. He studied Philosophy in his undergraduate work at Harvard and graduated from Harvard Law School. He was a federal Judge for the Southern District of NY from 1909-1924. In 1924 he was appointed to the 2nd Circuit Court of Appeals and remained there until 1961, the year of his death.
