On this day (October 10) in 1961, Anton Demmel was granted a US patent for the design of the Olympia SF small, flat portable typewriter – one of my all-time favourite typewriter designs.
Demmel designed most of Olympia’s 1950s typewriters, from the SG through the SM series down to the SF – and not just the outer casings.
Demmel had worked for Olympia in Erfurt before the war, but was one of the design team which managed to later rejoin Olympia in Wilhelmshaven in what was then West Germany.
SF, by the way, stands for schreibmaschine flach (flat typewriter).
Adwoa Bagalini reviewed this model two years ago and said, accurately, that it "is one of those ultra-portable machines that has received rave reviews from typewriter users".
"The SF is often mentioned in the same breath as the Smith Corona Skyriter and the Hermes Baby/ Rocket, as a typewriter that is both truly portable and pleasant to use."
Adwoa pointed out that the SF "appears to be a direct descendant of the earlier small Olympia portables, which were labelled Splendid 33, Splendid 66, and Splendid 99 in Europe, and in the States was seen occasionally branded as the Olympia Socialite."
On his Portable Typewriters Reference Site, Will Davis says that in 1957 "Olympia built a factory specifically designed to produce these [small flat] machines, and annual production jumped up considerably and stayed there. One of the very best of the flat portables ever made."
