Summer Street Bridge Streetcar Disaster occurs.

Forty-seven people drown when a streetcar traveling from South Boston to downtown Boston runs through a gate and plunges into the Fort Point Channel. It is described the next day by the Boston Globe as “The greatest catastrophe that has ever taken place in this city.” Motorman Gerald Walsh is subsequently accused of not stopping at a stop sign on the track and charged with manslaughter, but is later found not guilty.
