Life
Rothery was born in London. His father was William Rothery, chief of the office of the King's Proctor in Doctors' Commons. Henry was educated at St. John's College, Cambridge, where he graduated B.A. in 1840, as nineteenth wrangler in the mathematical tripos, and M.A. in 1845.[1] After leaving the university he entered Doctors' Commons, and from 1842 practised in the ecclesiastical and admiralty courts. On 26 November 1853 he was appointed registrar of the admiralty court. Soon after, he became registrar of the Privy Council in ecclesiastical and maritime cases. In 1860 he was made legal adviser to HM Treasury in questions and proceedings arising out of the slave trade. On account of his large experience gathered in the court of Admiralty, in 1876 he was appointed commissioner to inquire into the causes and circumstances of shipwrecks, and to conduct investigations into casualties at sea. He began his duties towards the close of 1876. His inquiries indicated many preventible causes of maritime losses.[2] His judgments on fire at sea in coal-laden vessels, on certain methods of stowing grain, on ship stability, and on overloading were especially valuable.
Tay bridge disaster
He chaired the public inquiry into the Tay Bridge disaster, when an express train was lost by the collapse of the 2-mile-long (3.2 km) bridge across the Tay estuary on the night of December 28, 1879. He was assisted by the Chief inspector of Railways, William Yolland and William Henry Barlow, President of the Institution of Civil Engineers. The inquiry sat initially in Dundee to hear eyewitness accounts of the accident, and then at Westminster Hall in London for expert evidence. They produced their final report in June 1880, and concluded that the bridge was "badly designed, badly built and badly maintained". Although they all agreed on the root causes of the disaster, his fellow judges Yolland and Barlow produced their own final report which hesitated in placing the blame on the chief engineer, Thomas Bouch. He himself died a few months after the inquiry reported in June 1880. The reports were made in a remarkably short time considering the wealth of evidence they had to consider. The remains were demolished and a new bridge built alongside the old with a double line of tracks.
