1860 Augustus Stroh took premises in London which he converted into a factory for the construction of the Wheatstone and Stroh instruments, at which place he designed and manufactured many instruments for the Post Office, besides working out many of his own very beautiful devices in aid of research or for demonstration of physical phenomena.
1880 These works were taken over by the Post Office, for which Stroh received a considerable sum, which enabled him to retire from business and to devote the whole of his energies to original work in connection with almost every branch of physical and mechanical science.
