The Manchester Mark I was one of the earliest electronic computers, built at the University of Manchester in England, in 1949.
The main Mark I team, Tom Kilburn and Freddie Williams, concluded that computers would be used more in scientific roles than pure math, and decided to start development of a new model including a separate floating point unit.
Among the Mark I team were mathematicians Conway Berners-Lee and Mary Lee Woods, who would later marry; their son, Tim Berners-Lee, is acknowledged as the inventor of the World Wide Web.
