Boris Vian was an engineer working for the AFNOR (french normalization body), which he found boring out of his mind. The first draft of L'Écume des Jours was written of AFNOR engineering graph paper.
Looks like one'd describe him as an insurance adjuster:

And of course, Wallace Stevens was an insurance lawyer.
