Introduction to Physics - signed by Joseph Grafton Gall

INTRODUCTION TO PHYSICS — Harley Howe McGraw‑Hill, 1942. First Edition, Fifth Impression. Owned and signed by Joseph G. Gall (National Medal of Science laureate). A solid wartime‑production physics text, printed under War Production Board restrictions (lighter paper, reduced margins). This copy carries the ownership signature of Joseph Grafton Gall, one of the most influential American biologists of the 20th century and a recipient of the National Medal of Science. Gall is renowned for pioneering work on chromosome structure and for co‑developing in situ hybridisation — a foundational technique in modern molecular biology. This makes the book a genuine scientific association copy, linking an early physics text to a major figure in cell biology. Suitable for collectors of the history of science, molecular genetics, or notable scientific libraries. Condition: Hardback, no dust jacket. Boards show general shelfwear and rubbing consistent with age. Interior clean and unmarked apart from Gall’s signature. Binding sound. A scarce opportunity to acquire a book from the personal library of a major scientist.…
