I was at the first Supercomputing conference at the Westin Bonaventure
Hotel in Los Angeles, with two of the four authors of the first BLAS
paper -- Charles Lawson and Fred Krogh. Fred asked the PR flack for
SAXPY whether he knew the origin of his company's name. He did not.
Richard Hanson had recently moved from the Jet Propulsion Laboratory to
Sandia National Laboratory in Albuquerque. I lost track of Dave
Kincaid. Sadly, Lawson and Hanson have passed away.
