Baker, Sir Benjamin (1840-1907)
Junior partner of Fowler with whom he designed the Forth Railway Bridge and other railway structures.

Bazalgette , Sir Joseph William (1819-91)
Built the first 1330 km (833 miles) of intercepting sewers in London from 1859 to 1875: also bridges and Thames embankments. IC E president 1884.

 Collaborator and partner of J. M. Rendell, well known for his Manual of Hydrology.

10. Belidor, Bernard Forest de (1693-1761)
 French mathematician and army officer whose engineering textbooks, used throughout Europe, were later updated by Navier.

11. Bell, Henry (1767-1830)
 A millwright who met Fulton, and in 1812 installed his 3hp engine in the Comet of 30 tons, which regularly covered the 112km (70miles) form Glasgow to Greenock until 1820. It was the first regular European steamship, but in the USA Fulton’s ships were earlier.

12. Berkley, James John (1819-62)
 After leaving King’s College, London, Berkley worked for G.P. Bidder; and from 1839 for Robert Stephenson. He went to India in 1850 as resident engineer for the first Indian railway, 1980km (1237miles) long, eastward from Bombay, But his health was ruined by the climate. He was awarded the Telford Medal in 1860.

13. Bernoulli, Daniel (1700-1782)
 One of an astoundingly brilliant Swiss mathematical family. His father, two uncles, two brothers and a nephew were all at one time professors of astronomy or maths at Basel. Daniel was the founder of mathematical physics but first studied medicine. His first papers in 1724,on fluid flow, probability, calculus and geometry, so attracted the St Petersburg Academy that he was invited there in 1725. His book Hydrodynamic a was published in Russia,

14. Bessemer, Sir Henry, FRS (1813-98)
 The son of a mechanical engineer who field from the French revolution, Bessemer was an extraordinarily versatile inventor who showed how to make liquid steel cheaply. British annual steel output rose a hundredfold from 50,000 tons. His first worked for a printer and developed his method of ‘ gold-plating’ to finance his other experiments.

15. Bidder, George Parker (1806-70)
 A child of astonishingly rapid mental arithmetic powers, taught at the age of six to count but only to 100. Wealthy people who had witnessed his calculations sent him to school, and to Edinburgh University, where he made a lifelong friend of Robert Stephenson, worked for him and helped him in his parliamentary battles by his fast calculations. He designed the Victoria Docks, London , a railway swing bridge and other engineering work. His son , a QC, and his grandchildren had similar gifts.
