So that's twenty-four individuals that count towards "(except for the moon of course in the '60s/'70s)"
Incidentally, as @ takintoolong just pointed out, the answer to Which astronaut travelled farthest from Earth? is the Apollo 13 crew. According to this answer:
Currently, the crew of Apollo 13 holds the record for highest altitude above earth with 400,171 kilometers (248,655 mi) on 7:21 pm EST, April 14, 1970 (source: Wikipedia). That would be 406,542 km when measured from the center of the earth.
All other known crewed missions have been in "paltry" LEO (low Earth orbit) as you call it.
You'd have to check each space station's maximum altitude to begin to start to look for maximum astronaut altitude excluding Apollo astronauts,
but I don't think it could possibly be farther than 500 km or so.
Update: Wikipedia sez:
Highest altitude for manned non-lunar mission
Gemini 11 crew Charles Conrad, Jr. and Richard F. Gordon, Jr. fired their Agena Target Vehicle rocket engine on 14 September 1966, at 40 hours 30 minutes after liftoff and achieved a record apogee altitude of 739.2 nautical miles (1,369.0 km).
But nothing even close to MEO or GEO. No reason at all (at least in my opinion and that of lots of others). Instead the focus is on robotic missions to "do stuff" out there in higher orbits. Robots can run for a long time, don't need air or water or bathroom breaks or space suits or sleep... mostly at least.
There was the planned Asteroid Redirect mission that early on had astronauts going into deep space, beyond the Moon, but you can read more about what happened to that in answers to What ever happened to the Asteroid Redirect Mission?.
