OK, this is not strictly only about Brooklyn. But it is too important for fans of brownstones and historic architecture in Brooklyn not to mention. On Tuesday, Sept. 25, the Greenwich Village Society for Historic Preservation will hold a panel discussion on the life and legacy of Charles Lockwood, author of the brownstone bible, “Bricks and Brownstone: The New York Row House 1783-1929.” As the panel announcement says, the book “spurred the brownstone revival of the late 20th century and was the first book of its kind to place row houses in historical context and examine how their architectural features tell their story.” The panel, called “Bricks and Brownstone and Beyond: A Panel Discussion on the Life and Legacy of Charles Lockwood,” will examine the continued impact of the book and the legacy of its late author. The panel will be moderated by Patrick Ciccone, a preservationist and Lockwood’s collaborator on the newly revised edition of the book. Panelists include Andrew Dolkart, architectural historian and author of “The Row House Reborn,” Kevin Murphy, architectural historian and author of “The Houses of Greenwich Village,” and John Foreman, real estate agent and author of the New York Social Diary’s weekly column “Big Old Houses.” The panel will take place at the Salmagundi Club, at 47 5th Avenue (between 11th and 12th streets in Manhattan). It is free but reservations are required. RSVP to firstname.lastname@example.org or 212-475-9585, ext. 35.
