FREDERICK WILLIAM CROHN was born in London on 3rd January 1831.
He was sent to school at Altona in 1842, and on his return to England in 1847 acted for two years as clerk to his father on the Corn Exchange.
In 1849 he again went to Germany for a course of study at the Polytechnic School, Carlsruhe, where he remained until 1853, winning excellent testimonials from the Professor of Engine-Building, and from the Manager of Carlsruhe Engineering Works.
From 1853-56 he was in the employ of the Carlsruhe Maschinenbaugesellschaft as draughtsman. During this period he was entrusted with various work in the construction of locomotives, including the plans for providing the different types of locomotive used by the Baden Railway with a uniform gauge; this was carried out in the Carlsruhe Works at the expense of the Archducal Government of Baden.
He then worked for eight months as constructing engineer under Jaques Messmer at the Graffenstaden Iron Works near Strassburg.
Returing to London, Mr. Crohn became a draughtsman in the office of Messrs. D. Napier and Son, Lambeth, from January 1857 to June 1860. He was then for six years chief draughtsman under Mr. J. Stewart at the Blackwall Iron Works, and from 1866-72 he was in private practice as a Consulting Engineer in London; during this period he took a prominent part in the construction of Messrs. Randells, Howell and Co.'s Steam Malt Works at Barking, Essex.
He subsequently returned to the Blackwall Iron Works for a period of nine years.
In 1881 he entered the firm of Messrs. Yarrow and Co., and took a very active part in the design of those classes of vessels to which this firm have devoted their special attention, his skill and ability adding greatly to the success of those vessels. He remained with the firm for over nineteen years, when he retired into private life.
His death took place at Bournemouth on 19th December 1915, in his eighty-fifth year.
He was elected a Member of this Institution in 1878.
