The author of the widely acclaimed, pro-socialist novel, The Harbor (1915), he also wrote the Pulitzer Prize-winning work, His Family (1917).
After graduating from Princeton University, he became a prominent journalist. His socially-themed articles argued for an end to child labor.
Many critics considered his Pulitzer Prize (awarded for His Family) to have actually been awarded for The Harbor, which was published before the Pulitzer Prize existed.
He was born in Chicago, Illinois. He died in New York City in 1950.
He and John Steinbeck were both recipients of the Pulitzer Prize for fiction. Steinbeck's pro-socialist novel The Grapes of Wrath won the prestigious honor.
