Missionary doctor, theologian, philosopher, organist, Bach expert, and winner of the Nobel Peace Prize (1875–1965). Vintage matte-finish 3.5 x 5.5 German postcard photo of a painting of Schweitzer, signed and inscribed in fountain pen in the blank lower margin, “À Madame Germaine Friedville avec mes bonnes pensées, Albert Schweitzer, 1954.” Tiny and subtle mark to emulstion in background, otherwise very fine, crisp condition.
