Henry Haworth Leslie (1845-1889)
1889 Obituary 
THE HONOURABLE HENRY HAWORTH LESLIE, who was born on the 19th of April, 1845, at Kenton, Devonshire, was the third son of Captain Martin E. Haworth Leslie (late 60th Rifles) and the Countess of Rothes. He assumed the surname of Leslie in 1886, on his mother’s succession in her own right to the Earldom of Rothes.
Educated at Charterhouse, he was apprenticed in 1863 to the late Mr. Robert C. May, of Westminster. During his articles he studied his profession at workshops in Birmingham and Middlesbrough, and was placed in charge of the construction of the gas-works at Ashford, in Kent.
In 1870 he went out for Messrs. Waring Brothers and McCandlish to the Honduras Railway. Here he was employed on difficult undertakings involving much hardship and dealings with people badly disposed to the railway.
On the suspension of the works in 1871, he returned to England, suffering from intermittent fever contracted in Honduras. Mr. Haworth was appointed an Assistant Engineer on the Madras Railway in 1873, was promoted after two years’ service, and in 1881 received pay and allowances as first-class Engineer. During the time of his work in India, he was three years in charge of the re-construction of the Cheyer Bridge, and two years in charge of the construction of the new bridge over the Pennair River, besides having had charge at one time or another of nearly every division of the railway during the worst time of the famine and floods.
Mr. Haworth Leslie returned to England in March, 1888, with his health much impaired, and died on the 15th of March 1889, in the forty-fourth yea of his age, much regretted by a very large circle of friends. He was elected a Member of the Institution on the 7th of February, 1882.
