1897 Obituary 
JOHN MALLABAND died at Sheffield on August 24, 1897, at the age of sixty-seven years. He left Coventry about the year 1857 and went to Sheffield, where he started as a moulder. He was appointed manager by the late Mr. Robert Hadfield on the establishment of the works now known as Hadfield's Steel Foundry, and afterwards became a director of Hadfield's Steel Foundry Company, Limited, a position he held at the time of his death. It was largely due to his great practical abilities that the company gained the high standing which they enjoy as manufacturers of steel castings.
Mr. Mallaband was elected a member of the Iron and Steel Institute in 1889.
"Death of an Early Worker in Steel Castings. - There occurred at Sheffield on Tuesday the death of Mr. Jno. Mallaband at the age of 67. Mr. Mallaband came to Sheffield about 40 years ago to work as a moulder. At that time several firms in the city were losing large sums of money in their efforts to produce sound steel castings, believing that there was a great future for such material.
After working for a few years Mr. Mallaband and a Mr. Forbes went into partnership in this business and lost all they had. Mr. Robert Hadfield, the founder of the Hadfield Steel Foundry, Limited, was, however, induced to take up the trade and engaged Mr. Mallaband as manager. The latter was a thoroughly practical man, and largely owing to his exertions success attended the manufacture of these castings, and their production is to-day one of the principal industries of the city. Mr. Mallaband, who was a member of the Iron and Steel Institute, was from the formation of the Hadfield Company to his death, one of the directors."
