QUOTE: "These portraits of Francis Guthrie and his wife were painted by their daughter, Louise. Francis Guthrie helped develop the railway connecting Graaff-Reinet to Port Elizabeth. He was also interested in flying machines, and he studied the wings and proportions of birds. He also lectured often on botany, and fourteen plant species are named after him.
