Leon O. Chua

He is the inventor and namesake of Chua's circuit one of the first and most widely known circuits to exhibit chaotic behavior, and was the first to conceive the theories behind, and postulate the existence of, the memristor. Thirty-seven years after he predicted its existence, a working solid-state memristor was created by a team led by R. Stanley Williams at Hewlett Packard.
Alongside Tamas Roska, Chua also introduced the first algorithmically programmable analog cellular neural network (CNN) processor. Provided by Wikipedia
