It was named for either Edward F. Winslow, president of St. Louis and San Francisco Rail Road, which owned one half of the old Atlantic and Pacific Railroad or Tom Winslow, a prospector who lived in the area.
The last Harvey House (the La Posada Hotel) opened in 1930. It was designed by Mary Colter. The hotel closed in 1957 and was used by the Santa Fe Railroad for offices. The city, which was a stop on the U.S. Route 66, has been served by I-40 since the 1970s. It achieved national fame in 1972 in the Eagles song “Take it Easy” which has the line “standing on a corner in Winslow, Arizona." The Santa Fe Railroad abandoned the La Posada in 1994 and announced plans to tear it down. It was saved and now caters to Route 66 fans.
