Remembering Ray Wu, DNA Sequencing Pioneer

This LA Times obituary reports the death of Ray Wu, a geneticist at Cornell University who made history in DNA sequencing and genetic engineering. Wu died earlier this month of cardiac arrest at the age of 79. He spent much of his time developing stronger rice strains that could withstand pests and drought -- and early in his career, "Wu developed the first method for determining the nucleotide sequence of DNA," according to the obit.

His contribution to DNA sequencing was not well known, laments Keith Robison, whose bog covers Wu's death.
