The Mount Stephen Club was a gentlemen's club located inside George Stephen House, built in 1880-1883. Considered a lair of the wealthy community of Anglophone Montrealers, It was founded in 1926 as a private business club for men by Noah Timmins, J.H. Maher and J.S. Dohan, and named after the house's first owner, George Stephen. Starting in 1964, women were allowed to come in by the same entrance as men, on Thursdays only, and in the-mid 1970s, women became equal members to men in the club.
