A lot of three items by prominent scientists, the first ROBERT FULTON (1765 - 1815) American engineer and inventor of the first practical submarine and torpedo, and established the first commercially successful steamboat, the Clermont, three closing lines detached from an A.L.S. 1p. oblong 12mo., [n.p., n.d.]: "Your civilities to him or assistance in case of necessity while he continues in France will much oblige me your sincere friend Robt. Fulton". Light staining, very good. With SIMON LAKE (1866-1945) American naval architect who invented the first submarine to operate successfully in the open sea, partly-printed D.S. 1p. oblong 12mo., Milford, Conn., Apr. 9, 1932, a check drawn on the Milford Trust Company making a $16.00 payment to Industrial Submarine Corps. Punch cancels lightly affect signature and engrossment, very good; and CLARENCE BIRDSEYE (1886 - 1956) American businessman and inventor of the process to quick-freeze foods, founded General Foods, signature and inscription on a small card, dated "5-21-48" and writing, "To Ronald Soderberg, a budding scientist - I hope".
