Hermann Maria Hauser, CBEFRSFREng FinstP CPhys, is an entrepreneur who was born in Vienna, Austria but is primarily associated with Silicon Fen in England.

When he was 15 he came to the United Kingdom to learn English at a language school in Cambridge. After his first degree in Physics from Vienna University, he returned to Cambridge to do a PhD in Physics at the Cavendish Laboratory.

He is probably most well known for his part in setting up Acorn with Chris Curry in 1978 (portrayed in the BBC drama Micro Men), and was voted the UK's 'Computer Personality of the Year' of 1984. When Olivetti took control of Acorn in 1985., he became vice-president for research at Olivetti where he was in charge of laboratories in the U.S. and Europe. In 1986, Hauser co-founded the Olivetti Research Laboratory (ORL) in Cambridge along with Professor Andy Hopper. Hopper became the laboratory's Director.

In 1988, Hauser left Olivetti to start the Active Book Company, investing one million pounds of his own money. Not wanting to repeat the mistakes made by Acorn, which had kept its technology to itself, he demonstrated the Active Book to as many large companies as he could. AT&T acquired Active Book and incorporated it into EO in July 1991. Hauser became Chief Technical Officer and Chairman of EO Europe. EO folded on Friday, 29 July 1994.
