James MacKenzie ( -1919) of David Rollo and Sons
1919 Obituary 
JAMES MACKENZIE, manager of the well-known firm of David Rollo & Sons, Fulton Engine Works, was educated in Glasgow, and served his apprenticeship as an engineer with Messrs. Walker, Henderson, general engineers, of Glasgow, being in charge of important departments before he had even completed his apprenticeship.
Whilst, still a very young man he was appointed chief draughtsman with Messrs. John & James Thomson, and thus brought into contact with marine work.
In 1885 he became chief draughtsman of Messrs. David Rollo & Sons, and shortly afterwards became engineering manager. He was pre-eminently a designer, and took the keenest interest in all developments of marine engineering. When in Glasgow he was an enthusiastic Volunteer, and when the Liverpool Scottish Battalion was formed in Liverpool, supported it very strongly.
The deaths of two of his sons in action, and anxiety as to the fate of his youngest son, who was severely wounded and a prisoner in Germany, had no doubt broken his strength, and he died after a few days illness on 19th February, 1919.
Mr. Mackenzie was elected a Member of the Liverpool Engineering Society on 13th November, 1895, and was also a Member of the Institution of Naval Architects.
