Keith Vivian Alexander is a New Zealand mechanical engineer and inventor. He is a professor of mechanical engineering at the University of Canterbury, in Christchurch, and the inventor of the springfree trampoline.
Alexander began his professional life as a primary school teacher. After 4 years of teaching he returned to university to complete a degree in engineering, conducting research on an invention of his own to gain his PhD.
Post graduation, Alexander worked for an engineering consultancy for a period of 6 years, in which time he led a team in developing advanced heavy presses for the New Zealand wool industry. Following this, Alexander moved to CWF Hamilton, a New Zealand company which pioneered the jet boat, where he worked on a number of projects including waterjet development which resulted in patented innovations. 1996 saw Alexander take up a position at the University of Canterbury where he still teaches mechanical engineering design & product innovation.
Whilst at the university he has been responsible for several patented inventions including the springfree trampoline. The trampoline won the 2010 Consumer Product of the Year Award in the United States following earlier awards in Australia, Canada and New Zealand. In the same year Alexander was awarded the New Zealand Engineering Innovator of the Year award by the New Zealand Engineering Excellence Awards.
