In 1880, Joseph Lapsley Wilson, a Civil War veteran and railroad executive, purchased land in the Philadelphia suburb of Merion. Over the next 40 years, he planted more than 200 specimen trees on the grounds of the property. When Dr. Barnes and his wife Laura purchased the land in 1922 for the purpose of building the Barnes Foundation, Wilson stayed on to assist with the development of an arboretum.
