Dr Alfred Bramsen was a dentist and art collector. He had a son called Henry.
Bramsen began collecting about 1870. He owned at least seventeen paintings by Vilhelm Hammershøi, whose works he began purchasing in 1889. He also owned pictures by Michael and Anna Ancher, Albert Gottschalk, Karl Jensen, Aug. Jerndorff, Viggo Johansen, P. S. Kroyer, J. Th. Lundbye, Jul. Paulsen, Th. Philipsen, L. A. Ring, Fritz Syberg and K. R. Zahrtmann.
Bramsen was greatly influenced by Whistler and made a number of references to him in his book on Hammershøi. He commissioned a portrait of Hammershøi's mother, Frederikke Hammershøi (1894, Private Collection) that showed affinities with Whistler's painting of his mother, which Hammershøi knew from reproduction.
About 1896 Whistler met Bramsen's son Henry in London. Henry gave Whistler some pictures by Hammershøi on his father's behalf (#11089).
