Friedhelm Hillebrand is a German engineer who has been influential in setting mobile telecommunications standards. As chairman of the non-voice services committee for the Global System for Mobile Communications standard in 1985, he conducted experiments to determine the length needed for text messages and found that 160 characters was sufficient.[dubious ] This subsequently became the basis for the 140 character limit now used by Twitter.[dubious ][1][dubious ]

He was born in Warstein in 1940, and even as a child, was active in amateur radio.[2] He gained a master's degree in telecommunications in 1968, then started his career with the German post office, which was then responsible for telephones too.[2] After retiring from that career, he started a consultancy advising on technology patents.[1] In 2009 he lived in Bonn.[1]
