Ambros Speiser

Ambrosius Paul Speiser (November 13 1922, in Basel – May 10 2003, in Aarau) was a Swiss engineer and scientist.

Speiser studied electrotechnology at Eidgenössische Technische Hochschule (ETH), where in 1948 he earned his diplom in communications engineering.

Under Speiser's technical direction between 1950 and 1955, Switzerland's first electronic calculating machine, ERMETH, originated.

The Schweizerische Akademie der Technischen Wissenschaften chose Speiser on 1987 as president of its executive committee and upon his resignation in 1993 made him an honorary member.
