In the first half of the 19th century, wealthy Baltimore was in love with art, especially art from Europe. Art historian Stanley Mazaroff tells of George A. Lucas, the son of one upscale family who was so enamored that just before the Civil War he moved to Paris and built a new kind of career -- as a transatlantic agent advising prosperous American collectors.Mazaroff's account of George Lucas' life as an art agent and collector is ----A Paris Life, A Baltimore Treasure----. He’s speaking about it next Thursday evening, July 19 at 7 pm at the Ivy Bookstore on Falls road.
