Wolfgang Krätschmer (born 16 November 1942 in Berlin) is a German physicist.
After his Diplom he went to the Max Planck Institute for Nuclear Physics in Heidelberg and earned his PhD there in 1971 with a thesis on artificially etched tracks of accelerated heavy ions in quartz.
In his career, he has worked on cosmic-ray heavy-ion tracks in lunar samples, as well as infrared and UV spectra of interstellar dust.
Together with his PhD student Konstantinos Fostiropoulos and with Donald Huffman from the University of Arizona, he developed a procedure[1][2][3] for the synthesis of fullerenes.
This procedure was the first to produce fullerenes in large amounts for chemical experiments.
