I was an undergraduate at Princeton, and I was pressed by the math department to go on to graduate school. Actually they gave me fellowships that paid my way, otherwise I would not have been able to continue.

With help from his uncle also named Alonzo Church he was able to attend the Ridgefield School for Boys in Ridgefield Connecticut. Church and Turing then showed that the lambda calculus and the Turing machine used in Turing's halting problem were equivalent in capabilities and subsequently demonstrated a variety of alternative "mechanical processes for computation.
