Alfred Joseph Casson (May 17, 1898 – February 20, 1992) was a prominent Canadian artist and a key member of the Group of Seven, known for his depictions of southern Ontario landscapes in a distinct, limited colour palette. Casson joined the Group of Seven in 1926, replacing Frank Johnston at the invitation of Franklin Carmichael. His ability to capture the unique Canadian scenery made him one of the most recognizable and influential artists in Canadian art history.  Born in Toronto, Ontario, Casson grew up in Guelph and Hamilton before moving back to Toronto in 1915. His passion for art was ignited during his time at Hamilton Technical School, where he first demonstrated his artistic talents. He began his professional career as an apprentice at a Hamilton lithography company at the age of 15, and later took private art lessons with Harry Britton, where he developed a love for watercolours.  In 1919, Casson moved to the Toronto-based firm Rous and Mann Ltd, where he worked under the mentorship of Franklin Carmichael, a founding member of the Group of Seven. Casson’s artistic skills flourished, leading to his invitation to join the Group of Seven in 1926. His contributions helped define the Group’s focus on portraying the Canadian landscape through simplified forms and bold colours.  Casson, along with Carmichael and F.H. Brigden, co-founded the Canadian Society of Painters in Water Colour in 1925. Throughout his career, he continued to work in commercial art, eventually becoming the Vice-President of Sampson-Matthews Ltd., before retiring in 1958 to focus on painting full-time.  Casson played a pivotal role in the formation of the Canadian Group of Painters in 1933, continuing the legacy of the Group of Seven after its dissolution. His work was characterized by clean lines, vibrant colours, and a focus on the landscapes of rural Ontario.  Throughout his life, Casson received numerous accolades, including being elected a full member of the Royal Canadian Academy of Arts in 1940 and becoming its president in 1949.  He was also honoured with the Province of Ontario Award, a Gold Medal for distinguished service in advertising, and the prestigious Officer of the Order of Canada in 1975.  A.J. Casson passed away on February 20, 1992, at the age of 93. He is buried at the McMichael Canadian Art Collection alongside other Group of Seven members, cementing his place as a cornerstone of Canadian art history.
