Once upon a time (in the middle 1960's) there was a man known as L. S. Detwilder who was at the very epicenter of the semiconductor test equipment development industry.
This man was known far and wide for his sage observations and uncanny insight covering the entire range of semiconductor test equipment.
He attended conventions and symposiums all across the world and was know to have contributed his comments widely on pertinent issues of the moment.
L.S.D. was credited with and by a number of articles appearing in trade magazines commenting on pertinent issues of the time.
Actually ..., L. S. Detwilder was a fabrication of the employees of Texas Instruments Semiconductor Test Equipment Developement group in Dallas.
As they traveled about the world (TI had 20 plants in 16 coutries at that time), they would fill out commment forms and such, signing each as "L. S. Detwilder".
And after a time an occasional article would appear in a trade magazine, quoting L. S. Detwilder as having made some profound remark.
Ever on the alert for satirical possibilities, I think the name and initials LSD were chosen as a refernece to the notorious halucinogen of the day.
