Mike Lesser (28 September 1943 – 1 July 2015) was a mathematical philosopher and political activist. He was born in London.
The youngest member of the Committee of 100, he was sent, aged sixteen, to Wormwood Scrubs Prison along with most of the Committee. He has served two spells as contributor to London's Underground journal International Times.
He was active in May 1968 in France.
In 1992 he was the co-author, with Prof A. Wuensche, of the book The Global Dynamics Of Cellular Automata, published in the "Santa Fe Institute's Reference Volumes". The book is an atlas of emergent forms evolving from the apparently chaotic product of a set of iterated logical operations.
