Francis Robbins Upton

Francis Robbins Upton (1852 in Peabody, Massachusetts – March 10, 1921, in Orange, New Jersey) was an American physicist and mathematician. Upton worked alongside Thomas Edison in the development of incandescent light bulbs, electric generators, and electric power distribution. He was the first president of the Edison Pioneers.

Francis Upton was the son of Elijah Wood Upton and Lucy Elizabeth Winchester. Elijah was well educated and after, he did European travel. Later he was forced to take over his father's glue business due to his father's illness. Francis was 16 by this time and studying at Phillips Academy in Andover, after he received a Bachelor of Science degree in 1875 at Bowdoin College in Brunswick, ME. There he met Elizabeth F. Perry, later to become his wife.

Francis Upton also attended Berlin University and Princeton University. Francis was the first ever to officially receive his doctoral degree from Princeton University. Upton was then hired by Thomas Edison. One of Edison's biographers described the hired man thus:

Upton married Elizabeth F. Perry in September, 1879, in Brunswick, Maine. Their daughter Elizabeth Fenno Upton was born August 24, 1880. Upton's sister Sadie, a frequent visitor in Menlo Park, is described as a "smart attractive lady with a distinguished swing".

Upton was hired by Edison in 1878 on the recommendation of Grosvenor Lowrey.

Edison was largely self-educated. He was brimming over with ideas but needed someone with advanced mathematical skills who could do calculations and research the scientific literature to help solve intractable problems. As Francis Jehl was also working with Edison, he needed another handle besides Francis for Upton:

The challenge of electric illumination was addressed:

Initially experiments ran currents through metals. Upton attended the 28th meeting of the American Association for the Advancement of Science and spoke "On the phenomena of heating metals in vacuo by means of electric current". Upton and Edison worked together on the incandescent lamp and in 1880 Upton reported on the history of electric lighting and Edison's lamp.
