An influential businessman turned legislator Lautenberg scored big victories in Congress including a ban on smoking on airplanes preventing domestic abusers from possessing guns cracking down on drunken driving and the Toxic Right to Know law about the release of pollutants into communities.
Frank Lautenberg has been one of the most productive senators in the history of this country Senate Majority Leader Harry Reid D Nevada said in December 2011 on the occasion of Lautenberg's 9 000th vote the statement by Lautenberg's office said.
On Monday political colleagues and foes lauded Lautenberg as a passionate advocate for the issues he championed.
He improved the lives of countless Americans with his commitment to our nation's health and safety from improving our public transportation to protecting citizens from gun violence to ensuring that members of our military and their families get the care they deserve said a statement by President Barack Obama a former senator.
Secretary of State John Kerry in remarks to reporters called his longtime fellow Democratic senator tenacious as a legislator and someone who never forgot where he came from.
In particular Kerry cited Lautenberg's advocacy for environmental issues and his spirited defense of Kerry's military record when it came under attack by Republicans in the 2004 presidential election campaign.
He was as loyal as he was patriotic Kerry said also noting how during the years when Frank was going through chemotherapy and he was weakened by cancer he was still down there on the floor of the United States Senate floor fighting on every environmental debate late into the night.
New Jersey's Republican governor Chris Christie told a GOP event on Monday that he often disagreed politically with Lautenberg but he respected the senator's battling spirit.
We had some good fights over our time battles on philosophy and the role of government Christie said. I think the best way to describe Frank Lautenberg and the way he would probably want to be described to all of you today is as a fighter. Senator Lautenberg fought for the things he believed in and sometimes he just fought because he liked to.
According to New Jersey law Christie can appoint a temporary replacement to serve until a special election in November or fill the rest of Lautenberg's term which expires next year.
With the likelihood that Christie will appoint a Republican the Democratic majority in the 100 member Senate would decrease to 52 along with two independents who caucus with the Democrats.
Possible GOP appointees would include state Sens. Thomas Kean Jr. and Joe Kyrillos a Christie ally who lost to Democrat Bob Menendez in the Senate race last year Lt Gov. Kim Guadagno and Assembly Republican Leader Jon Bramnick.
On the Democratic side Newark Mayor Cory Booker announced in January he intended to run for the Senate next year which caused a public tiff with Lautenberg who later decided against seeking re election.
The son of Russian and Polish immigrants Lautenberg grew up in Paterson New Jersey and enlisted in the military at 18 his office said. He was a member of the United States Army Signal Corps from 1942 to 1946 according to his biography.
After the military he graduated from Columbia University with the help of the GI Bill then joined with two boyhood friends to start payroll processing firm Automatic Data Processing or ADP which grew into one of the world's largest computing services companies.
Lautenberg was first elected to the Senate in 1982 and won re election twice. He did not seek re election in 2000 when his third term expired but was recruited to run again two years later after Democratic Sen. Robert Torricelli quit his re election bid weeks before the polls opened amid reports of ethical issues. Lautenberg was then re elected in 2008.
Survivors include his wife Bonnie Englebardt Lautenberg six children and 13 grandchildren the office statement said.
