Dr. Phil Andrews. Andrews was project director for the National Institute for Computational Sciences at the University of Tennessee at his death at 55 of a heart attack earlier this month.

Prior to Tennessee, Andrews worked for a decade as the director of high-end computing technologies at the San Diego Supercomputer Center at the University of California. His professional interests included artificial intelligence and 3-D software. But his interests did not stop at the edge of his lab.

He received degrees from Cambridge, Purdue and Princeton. At Cambridge he took part in track-and-field, throwing hammer, and played on the rugby team. After graduating and parallel to his professional life, he built a family and took up off-road racing and power-lifter. He was a published poet. Every death is a loss but holy crap, this guy was eight kinds of awesome.

Gregory Salgado. Salgado, a Cuban immigrant who built up several realty companies, including Real Renters LTD, Heim Realty and Structura LLC, died at 52. He was also a firm believer in the reality of technology. In the 1990s, he wired an apartment building in New York with the world's first residential T1 connection.
