Occasionally Typospherians comment that it’s nice for them to know who designed the particular devices they like on their typewriters – the Dowd-Hart “Magic Margin”, for example, and Joe Barkdoll’s paper support on the post-war Smith-Coronas.
Corona's design team in November 1953
One design I really like for carrying typewriters is the sturdy, secure yet lightweight case for these Smith-Corona Series 5 machines. It was designed by Aaron Charles Zeamer and James Edwin Harmon for Smith-Corona.
Aaron Zeamer (born Lancaster, Pennsylvania, June 15, 1915, died Bradenton, Florida, aged 91, September 5, 2006) and Jim Harmon (born 1908) worked for Smith-Corona in Groton much of their lives. Harmon was the son of Edwin Leander Harmon (1879-1945), who was a key designer for the Corona 4. In the 1940s, Edwin was typewriter inspector and Jim a typewriter assembler at Corona in Groton.
A competitor with the Corona 4 was the Underwood 4s of the early 30s and 40s, which also had fine, sturdy, secure cases. Indeed, Zeamer and Harmon referenced William Albert Dobson’s Underwood case design, which was patented on this day (October 4) in 1932, 80 years ago today. I posted on Dobson’s Underwood portable designs here.
Sturdy enough to take the Underwood on Rear Admiral Richard Byrd's Arctic flights
