David Hilbert:
(Königsberg (East Prussia), 23 January 1862 – Göttingen, 14 February 1943).
German mathematician who is considered one of the most influential mathematicians of the nineteenth and early twentieth centuries. His own discoveries alone would have earned him this honour, but it was his leading role in mathematics throughout his life and the “training school” he set up for promising young mathematicians, many of whom went on to become very important figures in the field, that really set him apart. For most of his career, he was a professor of mathematics at the University of Göttingen. Hilbert was also editor of the German mathematical journal Mathematische Annalen for a number of years.
Some people have a scope of view of radius zero and call it their point of view.
