BY the death of Mr. Bryan Donkin at Brussels on March 4 the engineering profession has lost one of its members who devoted himself with more than ordinary assiduity to the scientific side of his calling. The name of Bryan Donkin was eminent in the world of mechanical engineering for the whole of the last century. The late Mr. Donkin succeeded, in due course, to the management of the business which his grandfather, the first Bryan Donkin, had founded in 1803 for the manufacture of paper-making machinery; a new process for producing continuous rolls having been then recently introduced. Bryan Donkin, jun., as the subject of our memoir was known until quite recent times, was born in 1835, and was educated at University College, London, and at the École Centrale des Arts et Métiers in Paris, where he was for two years. After that he was apprenticed to his uncle at the Bermondsey works, his father, John Donkin, having died at a comparatively early age. In 1859 he went to St. Petersburg to superintend the erection of a large paper mill which was being established under the Imperial Russian Government for the manufacture of bank notes and State papers. He returned to this country and in 1868 became a partner in the Bermondsey firm. In 1889 the business was turned into a limited company, of which Mr. Donkin was chairman.
