John White Howell (* 22. Dezember 1857 in New Brunswick, New Jersey; † 28. Juli 1937) war ein amerikanischer Elektroingenieur.

The son of son of Martin Armstrong and Abigail Lucetta (Stout) Howell attended the College of the City of New York (1874-76), the Rutgers College (1876-1878) and the Stevens Institute of Technology (1878-1881) ), where he wrote his dissertation Economy of Electric Lighting by Incandescence.

In 1881, he joined the development department of the Edison Laboratory in Menlo Park and worked on the photometric measurement and testing of incandescent lamps and developed methods and procedures for their manufacture. In 1885 he published the results of his extensive tests of lamp life.

When Edison once again initiated a patent litigation process in 1890, the US Electric Lighting Company's lawyers argued that Edison's 1880 patent was invalid because the materials and methods described in the patent could not be reproduced. After two of Edison's lab technicians had failed in the attempt, Howell was entrusted with it. He succeeded in producing 30-40 working "tar putty" carbon filament lamps for the court.

From 1893 to his retirement in 1931 he was chief engineer of the Edison Lamp Works. Weblinks Edit sourcetext Standard data (person): LCCN: n88661233 | VIAF: 119939216 | Wikipedia People Search
