The book illustrates the development of the industry along the Rivers Tees, from the old Ironmasters鈥� District, through Port Clarence, North Ormesby and Cargo Fleet, down to South Bank, Grangetown and Eston. All the images have been painstakingly digitised and each photograph also contains a detailed description written by Dr Heggie.
'A lot of time and effort has been invested in this book and there is a great sense of achievement now it is finished,' said Dr Heggie, who was the British Steel Archive Project Manager from 2008 to 2011.
'The photographs paint a picture of what the industry and the area looked like and allows people to reminisce as well as learn something new - I think that is important.'
Middlesbrough鈥檚 Iron and Steel Industry is published by Amberley Publishing and, as well as paperback, is also available as an e-book, which opens up Middlesbrough鈥檚 heritage to people from around the world.
Dr Heggie added: 'This has been a fascinating project to work on. I don鈥檛 come from this area and when I first started looking into the industry it was all new to me. In a way that helped, as I did not have any pre-conceived ideas and had to go and find everything out for myself.'
So does Dr Heggie have a favourite image from the book? 'I don鈥檛 think I do 鈥� every single photograph in the book is unique and tells a special story about the heritage of this area.
'The photographs were all chosen, not just on the quality of the image, but because of the significant information they provide about the industry, the area, the people and the companies of this era. They can be looked at time and time again and each time you discover something new.'
