des RIVIÈRES, James "Jim" John McGill


January 10, 1953 – April 19, 2019

aka “Jeem” to many computing friends and colleagues 
and “Moth Man” to his Lepidoptera friends,

It is with great sadness that Jim’s family announces his passing in Ottawa, ON, on Friday, April 19, 2019. 

Jim will be sadly missed by his life partner Kathryn Finter. Jim was the son of the late Maureen (née Darwin) and late Major James Theodore (Ted) des Rivières. He is also survived by his brother Peter (Jocelyne), and sisters Ann (Graham) and Linda, as well as many nieces and nephews to which he was the best uncle a family could ask for. 

Jim, aka “Jeem” to many computing friends and colleagues and “Moth Man” to his Lepidoptera friends, will be fondly remembered by the many friends made over the years (Bell High School, Carleton University (as a Honours BSc graduate, computer programmer at the former Centre for Computing Services, and Assistant Professor), University of Toronto, Knights of the Lambda Calculus, Xerox PARC, Object Technology International (OTI), IBM, Photography Collectors Group, National Gallery of Canada, Camera Club of Ottawa, School of Photographic Arts Ottawa (SPAO) and the Museum of Nature) along with those gathered through his photography and mothing passion. Jim could always be found at the annual Live Butterfly Show at Carleton University where his large-scale moth or butterfly images were the backdrop for many photographs taken by families who attended over the years. Jim’s touring, Museum of Nature “Winged Tapestries: Moths at Large”, exhibit has been enjoyed at venues in Canada and the USA ( 

Jim gave all of himself to whatever endeavor he was involved in from his family, work and friends to his extra-curricular activities which took him around the world in search of adventure…and moths. He is irreplaceable and we will miss a very dear brother and a great friend. 

With appreciation to the great Oncology team at the Ottawa Hospital General Campus with a special thank you to Dr. X. Song and Dr. K. Drodge plus Dr. Wilkinson and Dr. Lotimer, all whose help and comfort during Jim’s treatment and short stay in hospital was invaluable. A private family visitation will be held followed by cremation. 

A Memorial Reception will be held at Capital Funeral Home and Cemetery, 3700 Prince of Wales Drive, Nepean on Saturday, May 4, 2019 from 2:00 – 4:00 pm. In lieu of flowers, please consider making a donation to a charity of your choice or, if you like, to School of Photographic Arts Ottawa ( – The Luna Bursary or The Sphinx Bursary, The CanaColl Foundation (, National Gallery of Canada – Photographs Collection ( , Museum of Nature – Insect Collection ( or Ottawa Field Naturalists (
