| Jan Hendrik Schon’s success seemed too
good to be true, and it was. In only four years as a physicist at Bell
Laboratories, Schon, 32, had co-anthored 90 scientific papers--one every 16
days--detailing new discoveries in superconductivity, lasers, nanotechnology and
quantum physics. This output astonished his colleagues, and made them
suspicious. When one co-worker noticed that the same table of data appeared in
two separate papers--which also happened to appear in the two separate
papers--which also happened to appear in the two most prestigious scientific
journals in the world, Science and Nature--the jig was up. In October 2002, a
Bell Labs investigation found that Schon had falsified and fabricated data. His
career as a scientist was finished. If it sounds a lot like the fall of Hwang Woo Suk--the South Korean researcher A. He cheated on the scientific papers. B.
