Firefighter James Shears, who also had the nickname of Britney, lived in Poole with his wife Carla and two sons, Ruben aged four, and Frankie, five.
He also lived near his parents, Marilyn and Ed, and brothers, Gary, Steven and Chas.
He joined Hampshire Fire and Rescue Service in 2003.
His widow said in a statement released today: ''My Jim was a hero in every aspect of his life.
''He was a truly dedicated hands-on father to his two boys he adored and who in return adored him.
''To me, Jim was a wonderfully caring, funny husband, my rock.
''I am not sure how we will cope without our Jim lighting up our lives but I find comfort in knowing his wonderful qualities will undoubtedly shine on through his gorgeous sons.
''On the 6th of April, I lost the most wonderful man I have ever known and heaven gained a hero.''
A memorial service is planned for both firefighters at Winchester Cathedral in July.
