TLS signed “Charles A. Lindbergh,” one page, 8 x 10, Long Barn letterhead, July 8, 1936. Letter to John Zwick of the Rockefeller Institute for Medical Research, in full: "Thank you for arranging to have the 220 volt A.C. motor built and shipped in time for us to use in Copenhagen this August. Because of your sending such excellent detailed lists I have decided not to go to Copenhagen until about the 3rd of August, although I had previously planned on going there this month. I have received a letter from Dr. Fischer to the effect that the boxed of equipment were in excellent condition when they arrived, and showed no signs of rough handling. I am particularly glad that it seems unnecessary to go to Copenhagen in July because the Institute is closed during July, and I think it would have caused Dr. Fischer considerable inconvenience if I had come this month." In fine condition. Accompanied by the original mailing envelope.
When his sister-in-law Elisabeth Morrow was discovered to have rheumatic heart disease in 1929, Lindbergh began a quiet collaboration with Nobel Prize-winning scientist Alexis Carrel on the development of a heart-bypass pump designed to enable open-heart surgery. Lindbergh corresponded regularly with the staff at the Rockefeller Institute, particularly John Zwick, one of Carrel’s main assistants, who dealt with any problems or modifications to the device. The result, a perfusion pump, was a hand-blown, 18-inch-high, clear Pyrex glass configuration devised to keep organs functioning outside of the body. Although Morrow sadly passed away in 1934, a year before the pump was completed, its creation served as a precursor to medical devices like the heart-lung machine, in addition to helping develop a practicable method for stopping the heart during surgical procedures. An exceptional letter relating to Lindbergh’s major contribution to the realm of biomechanics.
From the personal collection of a lifelong collector, teacher, and traveler with a passion for world history. His collecting years ranged from the 1970s to the present day, meaning that several of the premier pieces have not been on the market in decades.
