He moved with his father to Saline County, Kansas in 1885, and attended Salina Normal University in Salina, graduating in 1890. He taught school in nearby Bavaria in 1892 and 1893, studying law during his evenings and vacations. He was admitted to the bar in 1893, and practiced law in Salina for several years before moving to Kansas City, Kansas in 1900.
Four years later he was the Democratic nominee for Wyandotte County, losing in a close election. He won the office two years later, and was re-elected in 1908 and 1910.
He was elected in 1911 to the U.S. House of Representatives, filling a vacancy caused by the death of Alexander C. Mitchell, and was reelected twice.
