Julian Kennedy (March 15, 1852 - May 28, 1932) was an American engineer and inventor, known for his national and international contributions to the steel industry. He was awarded the ASME Medal in 1928.
Kennedy was born in Poland, Ohio in 1852, the eldest of the seven sons of Thomas Walker Kennedy and Margaret (Trusdale) Kennedy. His father was a prominent constructive engineer, inventor, designer and builder of blast furnaces.
After the Poland Seminary, he attended the Sheffield Scientific School, where he obtained his Bachelor of Philosophy in 1875. Later in 1900 he further obtained his MSc degree, and in 1909 his PhD from the Stevens Institute of Technology.
Kennedy started his career Morse Bridge of Henry G. Morse and his brother Charles James Morse. Kennedy was superintendent for the company from 1879 to 1883. Afterwards he moved to the Carnegie Brothers and Company at Homestead, later Carnegie Brothers and Company, where he was General superintendent from 1885 to 1888.
For another two years he was chief engineer at Latrobe Steel Works in Ligonier, Pennsylvania, before settling as independent consulting engineer in 1890 in Pittsburgh. He consulted many of the major steel plant in the United States and Europe. As a steel consultant, Kennedy helped launch the Russia steel industry with the construction of the Nikopul' Providence Steel Mill in 1896. In 1907, Kennedy built the first Indian steel mill for Tata industries, earning the nickname, "Father of Asian Steel." As such, Kennedy was a major figure in the growth and success of steel in four of the World's top ten producers: India, USA, Russia, and Ukraine.
