René Schoof

René Schoof is a Dutch professor of mathematics. According to Guus Razoux Schultz, Schoof was the original 1981 proposer of F2L, the speedsolving concept of using corneredge pairs to finish the first two layers of a 3x3 Rubik's Cube.
The CFOP method was known in the Netherlands as the "DockhornTreep system" (named after its developers (Kurt Dockhorn and Anneke Treep). It was published in 1981 by Frans Schiereck.[2] However according to Guus Razoux Schultz the F2L part of it had been developed by René Schoof.[3] Guus adopted F2L for his own CFCE method, and was the only competitor at the World Rubik's Cube Championship 1982 to use F2L.
Schoof is currently a professor of mathematics at the Università di Roma, specializing in number theory.
