Arthur Mignault, MD (29 September 1865 – 26 April 1937) was a French Canadian pharmaceutical entrepreneur, physician and colonel of the Royal Canadian Army Medical Corps, serving in the First World War.  He is the founder of the Royal 22e Régiment, today the largest regiment of the Canadian Army.Early life
Mignault was born in St-Denis, Canada East in 1865.
He graduated from medical school at the Université de Montréal in 1888, leaving shortly thereafter to practice in Maine.
Upon returning to Montreal in 1896, Mignault started a career in the pharmaceutics business.  He made his fortune by selling what he marketed as the petites pilules rouges (little red pills), a drug against anemia, intended for women's use.
A sports enthusiast and a horse racing amateur, he cofounded in 1901 the first French Canadian polo club.Mignault was a friend of artist and cartoonist Henri Julien. The latter's well-known gouache painting Le vieux de '37 seems to have been sponsored by Mignault, and as of 2009, the work is still in the family's personal collection. It has been hypothesized that the man pictured be Mignault's grandfather, Joseph-Édouard Mignault, a notary from Arthur's hometown who participated in the Battle of Saint-Denis of 1837 as a Patriote quartermaster.
Mignault gained notoriety as a philanthropist in 1909, as he offered some of his lands in downtown Montreal to establish a playground for poverty-stricken children.
In 1912, he married Béatrice Boyer, daughter of Canadian senator Arthur Boyer, and granddaughter of the wealthy Quebec land owner Louis Boyer. They had a single daughter, Valérie, born in 1914.
