Dr Michael Francis Tompsett is a British-born physicist, engineer, and inventor and is the founding director of the US software company TheraManager. In the early 1960s, he studied physics at the University of Cambridge and completed an engineering PhD.

He is a former researcher at the English Electric Valve Company, who later moved to Bell Labs in the United States. Tompsett invented CCD imagers and designed and built the first ever video camera with a solid-state (CCD) sensor. Tompsett received the Queen Elizabeth Prize for Engineering in 2017, along with Eric Fossum, George Smith, and Nobukazu Teranishi. Tompsett also received two other lifetime awards; the New Jersey Inventors Hall of Fame 2010 Pioneer Award and the 2012 IEEE Edison Medal. The thermal-imaging camera tube developed from his invention also earned a Queen's Award in 1987.

He made technological contributions in several different specialty areas including materials science, night vision, charge-coupled devices and integrated circuit design over a lifetime of work. This includes the in-situ monitoring of deposited epitaxial films, un-cooled night-vision thermal imaging camera tubes, un-cooled solid-state thermal imagers, CCD imagers and CCD cameras, MOS mixed analogue-digital integrated systems, and integrated video analogue-digital converters.
