On a snowy winter day in 1991, Lu Gang, a slightly built Chinese scholar who had recently received his Ph.D. in plasma physics, walked into a seminar room at the University of Iowa’s Van Allen Hall, raised a snub-nose .38-caliber Taurus pistol, and killed Professor Christoph Goertz, his thesis adviser; Robert A. Smith, a member of his dissertation committee; and Shan Linhua, a fellow Chinese graduate student and his rival.
Next, Lu went to the office of the chair of the Department of Physics and Astronomy, Dwight R. Nicholson, who was also on his dissertation committee, and fired three more fatal shots. Then, he walked over to Jessup Hall and demanded to see T. Anne Cleary, associate vice-president for academic affairs. When she emerged from her office, he killed her and then shot and maimed her twenty-three-year-old assistant. Finally, in an empty conference room, Lu raised the pistol to his head and killed himself.
Why a brilliant, hard-working young Chinese physicist, who had come to the US six years earlier filled with pride and hope, had come to such a bitter end is the subject of Dark Matter, a recently released feature film by Chinese-born director Chen Shi-Zheng. It stars Liu Ye as the initially idealistic and ambitious, then humiliated and enraged, protagonist (named Liu Xing in the film); Aidan Quinn as Liu’s arrogant faculty adviser (playing Christoph Goertz); and Meryl Streep as a kind, if naive, patron of the university who befriends Chinese students.
