Bern Dibner (18 August 1897 – 6 January 1988) was an electrical engineer, industrialist, and historian of science and technology.

Soon after graduating, Dibner designed and patented the first solderless electrical connectors and founded the Burndy Engineering Company in 1924.

He was an avid collector of original scientific works and of books on the history of science, as well as thousands of portraits of various scientists.

In 1941 Dibner formally established the Burndy Library as a separate institution "to advance scholarship in the history of science."

In 1976, the Smithsonian's Dibner Library of the History of Science and Technology[8] was established, providing the Smithsonian Institution Libraries with its first rare book collection, containing many of the major works dating from the fifteenth to the early nineteenth centuries in the history of science and technology including engineering, transportation, chemistry, mathematics, physics, electricity and astronomy.

The Huntington Library now offers a Dibner History of Science Program to fund fellowships, a lecture series and annual conference.
