Judy was born on 19 June 1943 and passed away suddenly from a cardiac arrest, on 1 July 2016, while shopping. She completed her Bachelor in Biology at the University of Waterloo in 1967, and spent her entire working career at the Canadian Museum of Nature (formerly known as the National Museum of Natural Sciences, Canada) in Ottawa, retiring in September 1997 after ‘30 years 1 month’.

Her early work involved the sorting and identifying marine invertebrates for the Canadian Oceanographic Identification Centre (NMNS/COIC; then called the Canadian Aquatic Identification Centre, CAIC). Through this experience, Judy became very familiar with essentially all marine invertebrates, which quickly led to her major interest in polychaetes. Then, in 1979, she was formally appointed as Invertebrate Zoologist (and then, Assistant Curator and Assistant Collection Manager) in charge of the non-crustacean collections, which included the National Annelid Collection.

Judy's first two publications were on tunicates and barnacles, but her first polychaete paper soon appeared (Fournier & Levings, Reference Fournier and Levings1982), and was quickly followed by eight peer-reviewed taxonomic articles over the next 12 years. Considering that her work was primarily about caring for collections and not so much about research, this was a fine accomplishment. Of those, we can highlight the description of new species, the arenicolid Branchiomaldane labradorensis (Fournier & Barrie, Reference Fournier, Barrie and Fauchald1987), scalibregmatid Axiokebuita millsi (Pocklington & Fournier, Reference Pocklington, Fournier and Fauchald1987), hesionid Microphthalmus coustalini and M. hystrix (Fournier, Reference Fournier and Reish1991), and dorvilleid Ophryotrocha spatula (Fournier & Conlan, Reference Fournier, Conlan, Dauvin, Laubier and Reish1994), as well as the redescription of Cossura longocirrata (Fournier & Petersen, Reference Fournier, Petersen, Petersen and Kirkegaard1991).

While Judy's career as a polychaete expert was relatively short, mainly due to her other curatorial responsibilities and the major move of the museum collections in 1996–97, she did leave more than publications. She was happy to collaborate with novices in polychaete taxonomy, helping them produce several papers. As a very good illustrator, she liked to provide her own illustrations to these papers.

For the Canadian authors of this obituary, representing the few remaining polychaete specialists in Canada, Judy was the Annelid person at the Museum when we first got involved in polychaete identification. Judy had an encyclopaedic knowledge of the polychaete literature and provided access to many obscure and difficult to find papers long before the World Wide Web, and brought about the translation of useful Russian literature. She was a real champion of Pat's work and encouraged her to pursue the idea of documenting the distribution of the polychaete fauna of eastern Canadian waters along both latitudinal and depth gradients. She also found some funding to support the project. This augmented the Museum collections with specimens from the Department of Fisheries and Oceans (DFO) Canada and the various consulting companies who sampled the eastern Arctic, Labrador, the Grand Banks of Newfoundland, the Gulf of St Lawrence, the Scotian Shelf and the Bay of Fundy. It is now an excellent resource for all polychaete taxonomists. Sadly, Pat's project could not be completed as no funding could be found to publish the results.

While at the Royal Ontario Museum, Sheila was invited by Judy to join a benthic collecting cruise organized by the DFO Ocean Ecology, Institute of Ocean Sciences (Patricia Bay, Sidney, BC) in the early 1990s. Benthic samples were collected from the majority of fjords along the BC coastline with specimens residing at both the Canadian Museum of Nature and the Royal Ontario Museum. Judy thrived on polychaetes almost as much as she loved horses. The in-depth conversations on problematic species were thoughtful and informative; generally followed up with relevant papers that prompted further discussion. She always looked at polychaete taxonomy as an investigative journey that gave her no end of energy and pleasure. Judy's passion was infectious and her support unwavering for those polychaete taxonomists lucky enough to know her.

For Val, Judy was a wonderfully generous woman when it came to sharing polychaete information, and assisting those learning the complex taxonomy of the west coast worms. Following intense discussion at the First International Polychaete Conference in Sydney, Australia, Judy became a great champion of tackling the ‘Cosmopolitan Species Disease’; Canada, as other regions of the world, being vulnerable to species misidentifications brought about through the use of out-of-area (e.g. European and South African) taxonomic monographs and keys. She was adamant about the importance of type localities, and checking those localities became a daily part of our identification routine. With the publication of more local atlases, the disease was mostly eradicated … or so we'd like to believe.

Judy participated in the first four International Polychaete Conferences from 1983 to 1992 establishing many long-lasting friendships with collection users and other researchers. Her severe hearing impairment never stopped her from communicating her knowledge and enthusiasm for polychaetes, or her distinctive sense of humour. She will be greatly missed by all who knew her.

For many years, Judy lived at Spiritwood Farm, North Gower, Ottawa and took part in many horse shows in the area. She loved her horse Erin and three cats, and her life on the farm. She is survived by her sisters Doris Crawford and Joan Corriveau. Her parents Sydney and Evelyn Rouse, and brother Sydney, predeceased her.
