Aug. 2, 1961 - The Manhattan brownstone in which Theodore Roosevelt was born in 1858 and the Victorian home on Long Island where he died in 1919 were offered to the Federal Government today by the Theodore Roosevelt Association as national monuments. President Kennedy applauded the association's donation and referred to the estate and birthplace as "priceless historical heritages." Theodore Roosevelt's birthplace contains the original furniture, the open porch on which young T.R. exercised to overcome his early frailty, and a portrait of his mother - a Confederate sympathizer who enraged the neighborhood by hanging the Confederate flag out the window during the Civil War. His 22-room estate in Oyster Bay, L.I. - Sagamore Hill - possesses the trinkets of his strenuous life. There are the tusks of the wild elephant he shot, the Rough Riders' hat he wore while charging San Juan Hill, and the head of the moose that charged him in Maine in 1911 but was shot down by him just in time.
