Morrison H. Heckscher, chairman of the American Wing of The Metropolitan Museum of Art, will be in Portland on Wednesday to talk about the preservation movement in New York and its similarities to the movement in Portland.

His talk, titled “The Preservation Movement in New York City: Parallels with Portland, Maine,” will help Greater Portland Landmarks celebrate its 50th anniversary. Heckscher will compare the plans of the two cities, including their Olmsted parks, and focus on the 1960s and the beginnings of preservation.

The talk begins at 6 p.m. Wednesday at First Parish Portland, Unitarian Universalist, 425 Congress St. Tickets cost $15, or $5 for students. A reception will follow, and tickets for the reception are available in advance at portlandlandmarks.org or by calling 774-5561.

Author of “Creating Central Park” and alumnus of Camp Kieve in Nobleboro, Heckscher has ties to Maine and a broad perspective on regional attitudes toward preservation.
