7548 Engström           Discovered 1980 Mar. 16 by C.-I. Lagerkvist at the European Southern Observatory.
Named in memory of Albert Engström (1869-1940), Swedish artist and writer. Born in Lönneberga in the Swedish province of Småland, he went as a student to Uppsala in 1889, where he studied Greek and Latin before his artistic ambitions made him move to an art school in Gothenburg. Probably Sweden's best painter of caricatures, he is best known for his black and white drawings illustrating very short stories. He was also an outstanding writer, specializing in short stories. Appointed professor of drawing at the Swedish academy of art, in 1922 he became a member of the prestigious Swedish academy.
