Doctor Emmett Lathrop Brown was a male Human Starfleet officer, physicist, and inventor in the early 23rd century.


Born in 2195 aboard the USS Columbus, he joined Starfleet in the early 2220s.

He held the positions of both chief medical officer and later science officer aboard the USS Copernicus. He later left Starfleet to be a physicist, and later an inventor. He was notable for devising the slingshot theory, the first method of time travel, along with his friend Martin McFly.

The USS Enterprise proved their theory in 2267, albeit accidentaly, with a previously uncharted black star. Both McFly and Brown were aboard the Enterprise during its second time travel the following year.

In the 24th century, the USS Emmett Brown was named after him.
