Edouard Zeckendorf
Edouard Zeckendorf (2 May 1901 – 16 May 1983) was a Belgian doctor, army officer and amateur mathematician. In mathematics, he is best known for his work on Fibonacci numbers and in particular for proving Zeckendorf's theorem: every positive whole number is either a Fibonacci number or can be written as a sum of distinct non-consecutive Fibonacci numbers (and such a representation is unique).
