Thorpe is an excellent multi-sport athlete, and if the OP didn’t set a 50 year timeframe, he hopefully would have been brought up by now. A few other older multi-sport names include former Celtic/Red Sox Gene Conley and The Rifleman Chuck Connors. Along with Thorpe, another comp is the Golden Greek, Harry Agganis...
Good one. I'd add Wilt Chamberlain. His NBA exploits are well known (mind-blowing actually), but he was the Big 8 high jump champ at 6'6" (at a time when the world record was 7 foot even), threw the shot over 53 feet (WR was around 62 feet), ran a sub 50 second 440 yd (WR was about 45 seconds); keep in mind he was doing these at the age of 18-19, at 7'2" and weighing nearly 250 lbs, and not specializing in any of them. He also played professional volleyball, and could bench press over 500 lbs (and was doing 450+ at age 60).
One last note on his NBA career; while they changed the rules to make it easier for Jordan (carrying or palming violations just disappeared), they changed the rules to make it harder on Chamberlain , such as widening the lane to where it is now and outlawing offensive goaltending (many alley-oop dunks currently allowed would have been offensive goaltending in those days).
Alleged bedroom gymnastics were not considered in this evaluation..
The Yankees could go 0-162 and it wouldn't be enough
