There have been times of both happiness and great sadness in the Hall Building--protests, celebrations, debates, and demonstrations, some peaceful, some not. The ninth floor was the scene of the Computer Riot in 1969, and the murder of four faculty members in 1992. The permanent art installation, a memorial to the people killed in the building, brought four large granite tables to the lobby. There were violent clashes in September 2002 between pro-Israeli and pro-Palestinian groups. Since 1966 countless students and staff, and the general public, have attended lectures, religious and ethnic celebrations, performances, and films, have eaten in the cafeteria and visited the rooftop greenhouse. Montreal’s first university art gallery opened here. Painted glass windows installed on the east side of the mezzanine were commissioned from eminent Montreal painter Jean McEwen (1923-99). The Concordia Theatre, formerly called the Douglass Burns Clarke (1908-80) Theatre, was dedicated to a member of the first SGW graduating class of 1937, who was also a teacher, Registrar, Vice-Principal, and Acting Principal of SGW; he believed the University should play an important role in the cultural life of the community. Thousands of people stream in and out of the building and onto its generous sidewalks daily and it is a part of the fabric of Downtown Montreal.
