An excerpt from 100 Things To Do In Portland, ME Before You Die by Robert Witkowski:
The photographer is Joseph Harrison Lamson (1840-1901) of Portland, Maine. The photographer’s father was a maker of daguerrotypes and his mother was an artist. He began his career in photography in Bangor, Maine and then worked in Cuba, the West Indies, and South America. He made a fortune and then bought a studio in Philadelphia, Pennsylvania. He then moved to Maine and operated a photographic studio in Portland. He photographed the poets Longfellow and Whittier. When he died, his two sons took over the studio.
The original St. Lawrence Church stood at 59 St. Lawrence St. It was named for the street, not the Saint. The street, in turn, was named for the Atlantic & St. Lawrence Railroad (as was neighboring Atlantic St.) which in turn was named for the St. Lawrence River, the railroad's terminus, which runs through Québec Province in Canada.
