MIT is a recurring motif in the works of Kurt Vonnegut, much like the planet Tralfamadore or the Vietnam War. In part, this recurrence may stem from Vonnegut family history: both his grandfather Bernard and his father Kurt, Sr. studied at MIT and received bachelor's degrees in architecture. His older brother, another Bernard, earned a bachelor's and a PhD in chemistry, also at MIT. Since so many of Vonnegut's stories are ambivalent or outright pessimistic with regard to technology's impact on humankind, it is hardly surprising that his references to the Institute express a mixed attitude.
