Jessica Fridrich is one of the inventors of the most common speed cubing method, the Fridrich Method. She also came second in the World Champoinship 2003 and tenth in the World Championship 1982.
Fascinated by puzzles and complex geometry, Fridrich has Rubik's Cube inventor Ernő Rubik's signature in her notebook, which he signed at the Rubik's Cube World Championship in Budapest in 1982, where she finished tenth. In the second Rubik's Cube World Championship in Toronto, Canada, she finished second, behind Dan Knights. In the speedcubing community she is considered one of the pioneers of speedcubing, along with Lars Petrus. Nearly all of the fastest speedcubers have based their methods on Fridrich's, usually referred to as CFOP (Cross, First 2 Layers, Orient Last Layer, Permute Last Layer).
Main Article: Fridrich Method
This method describes solving the cube in a layer-by-layer fashion. First a so-called "cross" is made on the first layer, consisting of the center piece and four edges. The first layer corners and edges of the second layer are put into their correct positions simultaneously (four pairs). The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms.
