Robert Pergl was a Czechoslovakian speedcuber. He won the second Czechoslovakian Rubik's Cube Championship in 1983, and was one of the fastest cubers of the 1980s.
Czechoslovakia was unusual in holding a second national Rubik's Cube Championship in the 1980s (the USA also held a second one). The second Czechoslovakian Rubik's Cube Championship took place in March 1983. Jiri (Jessica) Fridrich had won the championship the year before, but this time it was won by fourteen-year-old Robert Pergl, with a best time of 17.04 seconds.(note) This was the fastest time recorded in any competition in the 1980s, however it is not recognised by the WCA as an official record.
He used a similar layer-by-layer or CFOP method to Fridrich, but whereas Fridrich was actively using "about 120-150" algorithms, Pergl was using around 600. Pergl stated that his personal best single solve was 11 seconds, and his average-of-ten was 16.7 seconds.
Pergl studied law and works as a lawyer.
- Note: Some internet sources list his time as 17.02 instead of 17.04 seconds. A reliable source for his time is currently lacking.
