The family of Grenfell Tower fire victim Tony Disson has said losing him "left a void that can never be filled".
Mr Disson, 65, has been formally identified as a victim of the west London fire which killed at least 80 people.
The Metropolitan Police say it will be months before the final death toll is established.
In a statement, Mr Disson's relatives said he was "the heart and soul" of the family.
It said: "Losing him has left a void that can never be filled. Tony was the most generous person you could ever meet…He didn't have much but would always be there to help people.
"He had a great sense of humour, especially in the face of the practical jokes the boys would play on him.
"Tony was a real family man. His boys were his life. He was a loving husband, and a one in a million Dad."
The Fulham fan lived on the 10th floor of the building which was ravaged by fire in the early hours of June 14.
His son Alfie said: "Dad would take me, Harry and Charlie boxing from an early age, he would travel all over the country with us, and would be so proud of us whether we came home with a trophy or not.
"He was the best Dad a son could ever have, I couldn't have been prouder to call him my Dad. We love and miss him so much.
"He had a good life so to lose him in such a tragic way has made the loss hard to bear. We as a family are simply heartbroken."
Mr Disson is survived by four sons, five grandchildren - with a sixth due in September - and three great-grandchildren.
