German mathematician David Hilbert was first drawn to math inspired by his mother, who was a budding math enthusiast. He contributed to a host of concepts, theories, and postulates, such as Hilbert space, Hilbert's program, and Hilbert's problems. He died in oblivion, with a handful of people at his funeral.
