Panel 5 of Hyde Park Post Office Mural. From "Murals in the Hyde Park Post Office": "July 24, 1835. Dr. David Hosack and Miss Harriet Martineau drive a gig past Bard's Rock where the crew of a whaler roll casks of spring water to their ship. Dr. Samuel Bard's store and two dwellings face the river. Hosack (medical partner of Samuel Bard and Professor of Natural History at Columbia College) bought this place from William Bard in 1823 and between then and 1830 André Parmentier, a Belgian, said to be the first landscape gardener in the country, redesigned the property for him. It is the present Vanderbilt place." Hosack is perhaps most widely known as the doctor who attended to Alexander Hamilton after Hamilton's deadly duel with Aaron Burr. Harriet Myers identifies Martineau as a 33-year-old English social theorist who visited the 66-year-old Dr. Hosack in July of 1835. According to Myers, Martineau enthusiastically described the picturesque quality of Hosack's property, which Myers astutely associates with the role of Parmentier and the romanticism of the budding American landscape tradition.
