Philippe Maitrepierre (MS '66, PhD '69)

A CALTECH PhD in Materials Science, I eventually was the President and CEO of TECHALLOY Co.  
From 1990 to 2000 . TECHALLOY Company was the largest manufacturer of stainless steel and Superalloy wires in NORTH AMERICA, with sales reaching $ 130 Million in 1999, and  
6 facilities ( drawing mills) across the USA. 

Back in 1995 or 1996, my welding Plant in Baltimore received an order for a very special  
stainless welding wire in grade 316LSi, restricted chemistry, for the construction of the  
LIGO Observatory in Hanford. The order was for about 2000 lbs or so.  
It came to my attention and I gave instruction to monitor very closely the order which  
we delivered to LIGO's full satisfaction.

Very proud to have modestly contributed to this major achievement of CALTECH !
