13. Alan Turing, one of the pioneers of (theoretical) computer science, made many seminal scientific contributions to our field, including defining Turing machines, the Church-Turing thesis, undecidability, and the Turing test. However, his important discoveries are not limited to the ones I listed.
Turing machines, first described by Alan Turing in (Turing 1937), are simple abstract computational devices intended to help investigate the extent and limitations of what can be computed.uring proposed a class of devices that came to be known as Turing machines. These devices lead to a formal notion of computation that we will call Turing-computability. A task is Turing computable if it can be carried out by some Turing machine.
