This member of the famed Irish engineering family was probably the most famous bridge engineer in America in the early 20th century; his influential books include "A History of Bridge Engineering," "A History of Bridges," "An Irish Channel Railway," "Concrete Bridges and Culverts for Both Railroads and Highways," "Engineering of Shops and Factories" and "The Elizabethtown Bridge." TLS, 1p, 8½" X 11", Baltimore, MD, 1931 September 15. Addressed to Mary B. Day, librarian of Chicago's Museum of Science and Industry. Very good. Slightest bit of age toning. On Grattan Tyrrell and Company Engineers letterhead, Tyrrell fulfills a request for a copy of his most important book: "I take pleasure in forwarding you a copy of the book ["A History of Bridge Engineering"], the price of which since it was printed twenty years ago having been increased to $6.00 instead of $5.00 originally... This book was published privately by myself and I still have the latest edition... I therefore take pleasure in calling your attention to seven other books written by myself on various branches of Architecture and Engineering." Large, bold signature. Interesting and unusual.
