'Old Acres', the estate of Robert Bacon Sr., designed by John Russell Pope c. 1907 in Old Westbury. Landscaping was done by Martha Brooks Brown Hutcheson. The home burned to the ground after having been completed for only a week but was quickly rebuilt to the same plans. Bacon was a partner at J.P. Morgan and Co. and served as Assistant Secretary of State from 1905-1909, becoming Secretary of State for the final 38 days of Theodore Roosevelt's final term in office in 1909. He was the United States Ambassador to France from 1909-1912. The house was demolished in 1942. It sat somewhere on the Bacon property which ran north of Bacon Road between Jericho Turnpike and I.U. Willets Road.
