We give credit to Texas golf historian Frances G. Trimble for establishing the fact that Perry Maxwell, not John Bredemus, originally designed Colonial Country Club for Fort Worth businessman Marvin Leonard. Both architects submitted routings. Maxwell's was used, while Bredemus supervised construction. Colonial sported the first bentgrass greens in Texas when it opened in 1936. In 1939, the USGA awarded Colonial its 1941 U.S. Open, the first ever in Texas, so Leonard brought Maxwell back to toughen the course. He added 56 bunkers and created the present par-3 fourth and par-4 fifth (two of the famed Horrible Horseshoe trio of holes) and a par-3 13th (since replaced following a 1968 rechanneling of the Trinity River). Keith Foster's 2008 restoration wasn't to everyone's satisfaction. In 2023, Gil Hanse and Jim Wagner initiated a warp-speed, total renovation of the design using Maxwell's 1941 modifications as a roadmap, a similar treatment they implemented when remodeling Maxwell's Southern Hills in 2018, on display at the 2022 PGA Championship. This ranking does not reflect the Hanse/Wagner work: Their changes will be revealed in the 2027-'28 results.
