Time to call time on this one I think, given the absence of attempts. (I can't believe everyone's foxed - more likely no one wants to set the next question).
James Lowe started his railway career on the Great Western at Wolverhampton, before moving to Swindon. He then moved on to British Timken, before becoming an Inspector for South African Railways and Harbours. He left the railways to work for Rolls Royce in Derby, setting up his own engineering company after the Second World War. He is best remembered for his book "British Steam Locomotive Builders", first published by Goose & Son in 1975, a Supplement by TEE Publishing following in 1984.
So, we move on....
I'll try a new one, hopefully this is someone more widely known (or ought to be), and if you're current with kcart, you'll be well on the way there.
To title him as Railway Engineer, Locomotive Superintendent and later Traffic Manager hardly does justice to the pivotal role he played for a particular company. He was born in Basel, Switzerland, where his father was professor of English, but came to Bideford in Devon aged just eleven following the death of his parents. He served an apprenticeship for a firm best known for making steam cranes, but who also built several small locomotives.
In his mid-twenties he was appointed engineer and Locomotive Superintendent to the predecessor of the company he is best known for.
He turned his hand to many aspects of railway engineering and took out patents for various things from fish plates to wagon brakes. The high cost of timber in wartime led to innovations and further patents in the development of reinforced concrete structures - including signal posts and station name boards (but not hotels).
It is recorded that his wife came up with the distinctive livery bestowed upon the locomotives of his company, taken from the colour of a particular plant that grows widely in the region it served.
