I know the anniversary I have chosen to celebrate today on “Art’s History” will be one Prime Minister Justin Trudeau, in particular, will enjoy marking.  So, it was on this date in 1940 that our PM’s grandfather, the legendary James Sinclair, delivered his maiden address in the Commons.  Known as Jimmy Sinclair, the father of five daughters (including Margaret, who married then-PM Pierre Trudeau in 1971) was an impressive and successful fellow from an early age.He studied engineering at the UBC and later mathematics at the University of Oxford's St John's College on a Rhodes scholarship.  Still later, he attended Princeton University, where he studied mathematical physics. During World War II, he served with the Royal Canadian Air Force, ending his service time as a squadron leader.   A popular politician, widely known for his mainstreeting skills, James Sinclair would go on to be re-elected in the elections of 1945, 1949, 1953 and 1957.  From 1952-1957 he served as Minister of Fisheries Prime Minister St. Laurent’s cabinet.Click here to check out the Hansard containing Jimmy Sinclair’s rookie address.  caption id="attachment_558216" align="aligncenter" width="400" James Sinclair/captionArthur Milnes is an accomplished public historian and award-winning journalist.  He was research assistant on The Rt.
