Donald R. Huffman (1935 – November 2, 2025) was an American academic Professor Emeritus of Physics at the University of Arizona. With Wolfgang Krätschmer, he developed a technique in 1990 for the simple production of large quantities of C60, or Buckminsterfullerene. Previously, in 1982~1983, he and Krätschmer had found, in a UV spectrum, the first signal of C60 ever observed.
