Unsigned handwritten notes by Francis Crick, one page both sides, 6.75 x 9, dated August 3, 1966, from Crick’s nautical logbook used onboard his Bertram powerboat named the Eye of Heaven. The notes document his travels around Greece, noting times of arrival and departure, and tracking his fuel and oil levels. Among the destinations listed are "Egina," "Palaia Epidavros," and "Saronic Gulf." "Aegean," "Poros," and "Hydra." He makes some minor observations on the conditions, for example, "very calm (!)." In monitoring his fuel usage, he writes some fractions and does addition to determine how much he needs ("between 1/4 + 1/2 = 3/8 = need ~38…read = 16 need ~24, need ~62, ask for 60 gallons"). In fine condition. These notes date to just four years after Crick received the Nobel Prize for his discovery of DNA.
