 Westcott 's February 1946 photo portrait of Oppenheimer is highly regarded for depicting the Manhattan Project scientific director as a man weary from the tremendous weight of his experience . When he met with Oppenheimer , Westcott learned that the physicist wanted a cigarette but lacked the change to buy some . After Westcott gave him the money he needed , Oppenheimer bought his cigarettes and lit one . Westcott then captured the image of the physicist sitting next to a fireplace mantel in the Oak Ridge Guest House holding the freshly lighted cigarette in his hand .
