I only by chance yesterday learnt that William Tenn
recently died, on February 07, 2010, at the age of eighty-nine. Tenn was the nom de plume
of Philip Klass (May 09, 1920 –– February 07, 2010), who taught English/comparative literature at Penn State University for twenty-four years. He was an extremely good SF writer and satirist, even if most of of his output was in short stories.
