Boult, Wade, and Tennant

Boult Wade Tennant current logo

Boult, Wade, and Tennant was a firm of Chartered Patent Agents in London comprising Alfred Julius Boult, the founder, with Harold Wade and William John Tennant. Their address was listed as 111/112 Hatton Garden, London, E.C.

This firm still exists, incidentally. See Boult Wade Tennant on English Wikipedia.

"B. E. Dunbar Kilburn", that is Bertram Edward Dunbar Kilburn , joined the firm for a few years and apparently used the name Boult, Wade & Kilburn. Kilburn left at the beginning of 1906 (or the end of 1905) and went into practice on his own.

Regarding corporate evolutions, we do have cases in which the original has patent agent Alfred Julius Boult acting as applicant with Boult, Wade & Kilburn listed as patent agent.
