'''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.[https://web.archive.org/web/20180201163757/http://www.ws.binghamton.edu/fridrich/history.html] [[Jessica Fridrich|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.[[#cite_note-1|(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.[http://hlavolam.maweb.eu/sin-slavy]

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.[http://hlavolam.maweb.eu/sin-slavy]

Pergl studied law and works as a lawyer.[http://www.akdpp.cz/nas-tym/partneri/mgr-robert-pergl/]

==Footnotes==
*Note: Some internet sources list his time as 17.02 instead of 17.04 seconds. A reliable source for his time is currently lacking.

'''Ronald Brinkmann''' (sometimes mispelled as ''Roland'' Brinkmann[[#cite_note-1|(note)]]) was a German speedcuber. In 1982 he won the West German Cubing Championship, and finished fourteenth in the [[World Rubik's Cube Championship 1982|1982 World Championship]].

Brinkmann came from Harburg, Hamburg, West Germany. At the age of 16 he first solved a Rubik's Cube which belonged to his maths teacher: the teacher had given-up, but Brinkmann solved it overnight. On 6-13 March 1981 a Guinness Book of Records speedcubing tournament took place at the Olympia Shopping Centre, Munich. Brinkmann was joint winner (with Jury Fröschl) with a best time of 38 seconds. He also achieved 29 seconds on German TV and before the end of 1981 reached 24 seconds.[https://www.jaapsch.net/puzzles/cubic1.htm]

He won the first West Germany Championship in 1982 with a winning time of 19 seconds.[https://www.jaapsch.net/puzzles/cubic3.htm] This has sometimes been reported as a world record time.[https://web.archive.org/web/20170303183813/https://www.bestspeedcubes.com/speedcubing-world-records/] If so, it was broken by March 1983, when [[Robert Pergl]] won the 2nd Czechoslovakian Championship with a best time of 17.04 seconds.[https://web.archive.org/web/20180201163757/https://www.ws.binghamton.edu/fridrich/history.html]

The [[World Rubik's Cube Championship 1982]] took place on June 5. Brinkmann was, according to [[Guus Razoux Schultz]], the favourite to win.[https://web.archive.org/web/20180330002313/https://www.ws.binghamton.edu/fridrich/gus.html] However, the tournament used stiff cubes which favoured those using more efficient methods. Brinkmann ultimately finished in 14th place with a best time of 30.59 seconds. According to [[David Singmaster]], Brinkmann used two methods: one was a [[Corners first]] technique (DC, UC, U & D E, ME); the other was DC, 3DE, 4UC, rest.[https://www.jaapsch.net/puzzles/cubic3.htm]

==Footnotes==
*His name ''Ronald'' is verified by the testimony of David Singmaster;[https://www.jaapsch.net/puzzles/cubic3.htm] [[Georges Helm]] (who owns Brinkmann's solution guide);[http://cube.helm.lu/myweb/cubbibs.htm] and the 1983 Guinness Book of Records.[https://books.google.co.uk/books?redir_esc=y&id=WqUxAQAAIAAJ&dq=%22ronald+brinkman%22+rubik&focus=searchwithinvolume&q=%22ronald+brinkman%22] The [[WCA]], as of 2025, continues to list his name as ''Roland''.
