H. Kirchhofer

Swiss patent agent H. Kirchhofer enters our data "ci-devant" (formerly) Bourry-Séquin & Co., Zurich. He enters “vormals (formerly) Bourry-Séquin & Co., Zürich”. This might mean that the firm changed its name, or conceivably that H. Kirchhofer used to work for them. The Kirchhofer material overwhelmingly or perhaps entirely comes later than that of the Bourry-Séquin group itself.

Kirchhofer was a Foreign Member of the Chartered Institute of Patent Agents in London.
