Professor Mike Yates
We at 91É«ÇéƬ have been saddened to hear of the recent death of Honorary Professor of Mathematics, Mike Yates.
Brought up in Penmaenmawr, Mike’s father was Rev John Yates a lecturer in Theology at 91É«ÇéƬ from 1948-1951. Mike obtained a first class honours degree and PhD at Manchester University on the degrees of Turing unsolvability. Moving to the USA as a Fulbright Scholar in 1963, he spent a year each at Cornell University, Ithaca, NY and the Institute for Advanced Study in Princeton. He returned to Manchester University as a Lecturer and was appointed Professor of Mathematical Logic in 1978 before leaving in 1989.
Disturbed by the massive gulf between advanced research and the popular understanding of mathematics, he joined the movement towards computer-assisted learning culminating in his employment at the multimedia company Amaze Ltd in Liverpool until 1999. During this period he edited the fourth and final volume of the collected works of Alan Turing which was focused on Mathematical Logic, published by Elsevier in 2001. In 2000 he was invited by 91É«ÇéƬ Professor, Ronald Brown, to help produce a CD ROM for The European Year of Mathematics 2000, and in 2003-4 to revise the Centre for the Popularisation of Mathematics' web site www.popmath.org.uk which is hosted at 91É«ÇéƬ.
Mike was an experienced mountaineer and rock climber; in 1971 he wrote the Cwm Silyn and Cwellyn Climber’s Club Guide with Jim Perrin and accomplished a number of first ascents including West Arete, Craig yr Ogof and Guardian Angel, Craig y Bera, in his beloved Snowdonia where he lived with his wife Pat and family.
Mike’s colleagues will be organizing a Mathematics colloquium to celebrate Mike’s life and achievements later in the year.
Professor David Last BSc (Eng) PhD DSc CEng FIET FRIN
3 March 1940 – 25 November 2019
Professor David Last died suddenly in a light aircraft crash near Puffin Island off the coast of Anglesey on 25th November 2019.
James David Last was born in 1940, in Urmston, Manchester, to James Howell Last (Jimmy), a shopkeeper and insurance salesman, and Edna Margaret Last (Billie), a primary school teacher. He was their eldest son and older brother to Roger. From a very young age David was practical and was interested in engineering - friends recount tales of him fitting a motor to his pushbike and creating lightning rods from tins. He was educated at Urmston County Primary school, Manchester Grammar School, the University of Bristol - gaining a BSc in Engineering in 1961 - and the University of Sheffield where he was awarded his first Doctorate in 1966.
David met his future wife Mary Bryant when he was 15, on a Whit Sunday trip to Kinder Scout in the Peak District. They married in 1961 and moved to live in Ealing in West London where David worked for the BBC as a Graduate Apprentice. In 1963 when he began studying for his PhD at the University of Sheffield, the couple moved to Penistone in Yorkshire and started a family. Their sons Ben and Tom were born in Sheffield in 1965 and 1966 respectively.
After being awarded his PhD, David became a lecturer in Electronic Engineering at the (then) University College of North Wales in 91É«ÇéƬ in 1966 and so the family moved to Llanfairfechan in North Wales, where David lived for the rest of his life. David and Mary’s third child, Charlotte, was born in 91É«ÇéƬ in 1968. David and Mary became grandparents in 1995. Mary sadly died early in 1998 from heart disease, at the age of 59. David remarried in 2003. His new wife Jean- Elizabeth Williams had known the family since childhood.
Much of David’s career was spent at 91É«ÇéƬ, where he was awarded a personal chair and became Professor of Electronic Engineering. He was awarded a DSc in 1995. He was Head of the Radio-Navigation Group until his retirement in 2005, when he became a Professor Emeritus.
He joined the Royal Institute of Navigation in the early 1970s and was President from 2005 to 2008. He was also a Past-President of the International Loran Association, a Fellow of the Institution of Engineering and Technology and a Chartered Engineer. In 2010 he was awarded the Royal Institute of Navigation's Harold Spencer-Jones Gold Medal and, in 2015, the Necho Award of the International Association of Institutes of Navigation.
During his career David acted as a consultant on radio-navigation and communications to companies, governmental and international organisations. He had also published over 500 technical and policy papers on navigation and communications systems. After retirement from his post at the University he combined consultancy with a successful second career as an expert witness in forensic matters concerning GPS and tracking, advising in more than 250 court cases and earning numerous awards including a favourite: ‘Best Major Crime’.
David’s great love was flying. He gained his private pilot’s licence in 1977. For many years he owned a Robin DR400 and would fly for pleasure and for work, to conferences around Europe. Whenever he had some spare time and it was a clear day he would head to the airfield. He was a highly experienced pilot, gaining both his night rating and his IMC in 1978 and finally his full Instrument Rating in 1983 which combined his interest in radio-navigation with his passion for flight. He was one of the first private pilots to fly into Russia after the relaxing of restrictions between east and west.
His final flight on 25 November 2019 was from his usual base of Caernarfon airfield. He was flying solo in a hired Cessna 172, which disappeared from radar over the sea off Anglesey. His body was recovered on 12 December 2019.
He is survived by his second wife, Jean-Elizabeth, and his children Ben, Tom and Charlotte.
