Does anyone have information about Piquet and Calitet (chemists)? I was given a set of names of chemists to research and one of them was actually a duo that I understand to have been French chemists (at least their last names suggest it). I have queried and queried not simply Google, but also academic databases (Wiley, ProQuest, Elsevier, etc.), yet I've found nothing.

I believe I am spelling the names correctly, but for clarity, phonetic expression of their surnames is:


  "PEA-ket and CAL-ee-TET"


Hath anyone information on these names within chemistry (or similar natural science discipline)? It would allow me to end a nearly two month search – one way or another.

Most appreciative for any corrections if I have erred in spelling, nation of origin, etc.
Can you exclude spelling errors? If not, there is


Amé Pictet, known from the Pictet-Spengler cyclization.
Claude Piguet, an inorganic chemist at the University of Geneva. 


Both were/are is Swiss, not French.

However, the second name does not ring a bell for me.
