Dan Biddle, 32, took the full force of the bomb detonated by terrorist Mohammad Siddique Khan, 30, in the carriage of his tube train at Edgware Road during the 7/7 atrocities.
His life was saved thanks to the heroic action of South African Adrian Heili, 31, a former soldier, who rushed to his aid, stemming the bleeding from the stumps where his legs had been, and staying by his side until the emergency services arrived.
Now Mr Biddle has named his newly born son in Adrian's honour.
Little Nathan has the middle name Adrian because, Dan tells the Sun: 'I owe the man everything I've got now and for the future.'
The explosion in Dan's carriage on July 7 2005 killed six passengers and blew him out through the doors of the tube, off against the walls of the tunnel, and left him lying on the tracks, before the doors broke off the train, slicing through his legs.
He was the worst injured survivor of the Edgware Road bombing, and was in a coma for six weeks before spending a year recovering in hospital.
Since the events of 7/7, Dan has rebuilt his life, working as an accessibility consultant, and enjoying life with his 31-year-old wife Lisa and their two children, two-year-old Caitlyn and newborn Nathan Adrian in Romford, East London.
He told the paper: 'I phoned Adrian soon after the birth and said something like, 'I hope you don't mind but I've named him after you'. It choked him up a bit.'
What a lovely story to come out of such tragic circumstances.
