Item #24444 Autograph Note Signed. James J. "Crash" RYAN.

Autograph Note Signed.

Auto safety pioneer long before Ralph Nader popularized the topic in "Unsafe at Any Speed," this University of Minnesota mechanical engineering professor (1931-63) patented the first retractable safety seat belt in 1963 and the "black box" flight recorder in 1960; he also improved hydraulic bumpers, dashboards and collapsible steering columns. ANS, 1p, heavy stock 6¼" X 3¼", n.p., 1971 July 23. Near fine. Penned boldly in blue ballpoint. Nice note thanking an admirer and "enclosing the last publication before retirement." Closes off with a true crusader's salutation: "Please carry the program forward." A quite uncommon autograph. Item #24444

Price: $125.00
