Based in New York, she joined the network in 2000, after hosting CNBC's "The Money Club" and serving as the network's Washington correspondent.
Buttner graduated with honors from Harvard University with a B.A. in social studies and went on to become a Rhodes Scholar at Oxford University, where she graduated with high honors in politics and economics.
Neil Cavuto offered a heartfelt tribute to Buttner on "Your World," praising her intelligence, heart and sense of humor.
"She took stock of life much more than any stock in life," Cavuto said. "It's what separated her from everyone else in this business. Not just dollars, you see, Brenda had depth."
"Let it be known that Brenda Buttner made us want to watch a business show with heart. Her heart, her spirit," Cavuto said. "She democratized dollars and just made sense."
"Business journalism is never going to be the same. I just don't know, now that she's gone, whether we'll ever be. Brenda Buttner, gone way too soon at 55."
Brenda Buttner, Fox News host, dead at 55 after cancer battle
Brenda Buttner, the longtime host of Fox News’ “Bulls & Bears,” died Monday after a battle with cancer.
She was 55.
The financial reporter, who graduated from Harvard University in 1983 and spent two years as a Rhodes Scholar at Oxford University, got her professional start at an NBC affiliate in Reno, Nev., before hosting CNBC’s “The Money Club” and serving as a correspondent from 1990 to 1998.
The New Jersey resident joined Fox News in 2000 and served as a senior business correspondent and host of “Bulls and Bears.”
“Women are not afraid to simply admit they don’t know about something, which men rarely do,” she told the Fort Lauderdale Sun Sentinel in 1997. “So women realize there is no such thing as a stupid question when it comes to understanding an investment.”
Fox News host Neil Cavuto honored his colleague on the air Monday.
“In her sickest moments, battling an unrelenting cancer, there was Brenda, cheering you on,” he said.
“Business journalism is never going to be the same. I just don’t know, now that she’s gone, whether we’ll ever be.”
Former Fox News commentator Tobin Smith remembered Buttner in a touching Facebook post.
“She loved rainy days, cloudy places, motorcycles and her children most of all. I told her that I would spread a few of her ashes in her beloved Edinborough outside her favorite pub...she loved that idea. She called me her ‘office husband’ and I told her that ‘all I got was c--p from her and none the benefits’ and she would laugh a hearty obscenity in response,” he wrote.
“My role in her life the last few years was to make her laugh...and I accomplished that goal on many phone calls. She was the type of friend you could not speak with with for months and then talk like we had just left off from yesterday.
“My dear Brenda Buttner..she was the little sister I never had. I miss her terribly and yet she is in my heart forever and an inspiration to all that knew her and her battle.”
Former CNBC anchor Ted David said Buttner was "fiercely smart but equally upbeat, full of fun and superior on the air."
"She was smarter than smart, poised and gracious on the air, fun to work with as a fellow broadcaster and dedicated to her job," he told the Daily News. "She was a mom, a motorcycle lover and person full of life. Her death is beyond sad and reminds us that life is precious and we must defeat cancer in out time."
'Business journalism is never going to be the same': Fox News presenter Brenda Buttner dies aged 55 after cancer battle
Fox News correspondent Brenda Buttner died Monday aged 55 after a cancer battle.
Tributes poured in for the long-time host of the network's financial segment 'Bulls & Bears'.
Colleagues painted the picture of a modest intellectual, far more concerned with the little things in life, who inspired many with her sharp wit and caring nature.
For eight years from 1990 to 1998, she hosted CNBC's 'Money Club' before joining Fox News in 2000 where she remained for the last 17 years.
Buttner famously told the Fort Lauderdale Sun Sentinel in 1997: 'Women are not afraid to simply admit they don't know about something, which men rarely do, so women realize there is no such thing as a stupid question when it comes to understanding an investment.'
Fox News host Neil Cavuto commented on the quote as he announced her passing on his show, 'Your World' on Monday evening.
He added: 'The thing is, Brenda didn't ask stupid questions.
'She asked real questions, and woe to the guest who wasn't ready for them. Brenda kept scores without ever having to settle scores.
'Everyone deferred to her, everyone listened to her. Maybe because everyone respected her.'
He joked that he and Brenda's colleagues said that hers was a 'different bucket list in life' - one that made you consider your own values.
'In her sickest moments, battling an unrelenting cancer, there was Brenda, cheering you on,' he said.
'Business journalism is never going to be the same. I just don't know, now that she's gone, whether we'll ever be.'
'Brenda's captured what really mattered in life,' he said.
For Brenda, that was her daughters, animals, and her surprising love of motorcycles.
'No bravado, just brave,' Cavuto continued.
Fox News contributors Julie Roginsky and Nomiki Konst also tweeted their heartbreak at the news of Buttner's passing.
The reporter graduated near the top of her class at Harvard University and spent two years as a Rhodes Scholar at Oxford University in the 1980's, according to Fox News Insider.
