It was the first of three books he would write on power and mechanical engineering. In 1958 Stephen’s Synchronous Motors and Condensers was published. Stephen retired in 1994 as a director of engineering at BTH. He helped design, install, and test large bulk carriers and tankers including the SS Canberra and the HMS Challenger. Aluminum smelters extract refined metals from ores. While working at the company, he was the principal engineer for several large-scale projects including the Lochaber Aluminum Smelter installation in Scotland-the last plant of its kind in Britain. He joined BTH in 1942 after receiving a bachelor’s degree in engineering from the University of Glasgow. Stephen served in leadership positions at electrical equipment manufacturer British Thomson-Houston, in Rugby, England.
He earned a bachelor’s degree in electrical engineering in 1947 from the University of British Columbia, in Vancouver. He then was honored with the 2017 IEEE Kaufmann Award for outstanding contributions to industrial systems engineering. Hesla received IEEE Member and Geographic Activities’ 1998 IEEE Wilson Transnational Award. He was also an entrepreneur, founding two Washington state–based companies: consulting firm Hesla and Associates, on Camano Island, and electrical engineering firm EngePower-USA, in Edmonds. When he returned to the United States, he became an assistant manager at a construction firm. Later he moved to Brazil and worked as an engineer on large hydroelectric projects. Hesla began his career in the late 1940s at a Canadian engineering firm, where he worked in manufacturing and sales support. It was the first IEEE standard to provide guidance for safe workplace practices regarding industrial electrical systems. Hesla was dedicated to improving electrical safety and the development of IEEE Standard 902-1988: Guide for Maintenance, Operation, and Safety of Industrial and Commercial Power Systems. in physics in 1970 from the University of Manchester. The University of Maryland recognized him with awards including the 2015 Lin Innovation Award, the 2014 Senior Faculty Outstanding Research Award, and the 2012 Poole and Kent Senior Faculty Teaching Award.ĭavis was a Fellow of the Institute of Physics and SPIE, the international society for optics and photonics.Īfter receiving a bachelor’s degree in natural sciences in 1965 from Cambridge, he went on to earn a master’s degree there, then a Ph.D. It is scheduled to fly to the moon this year aboard a Firefly vehicle.ĭavis was an active member of an IEEE coordinating subcommittee that developed standards for testing wireless phones to ensure they comply with international standards designed to protect the public from harmful RF exposure. The device enables more precise measurements of the distance from the Earth to the moon, allowing better mapping and navigation of the moon’s surface. In 2019 he and his Maryland colleagues developed a lunar retroreflector-an instrument placed on the moon that reflects laser pulses sent from Earth back to their origin point-for NASA. He authored or cowrote textbooks including Lasers and Electro-optics and Building Scientific Apparatus. His research focused on RF communications systems, advanced surveillance systems, chemical and biological sensors, and optical systems. He left two years later and joined the faculty in the University of Maryland’s electrical and computer engineering department. Davis taught engineering at the University of Maryland in College Park for 48 years.īorn in Manchester, England, he moved to the United States in 1973 to work as an instructor and research associate at Cornell.
