This included actor Patrick Stewart, of "Star Trek: The Next Generation" fame; Boston police public information officer Cheryl Fiandaca, who used Twitter to keep the community informed during the Boston Marathon bombings; and 9-year-old Vivienne Harr, a fourth grader from Marin County.
Vivienne was chosen to share Twitter's big day because company execs are impressed with her efforts to help end the modern day slavery of children her age.
Ringing the bell at the NYSE is an honor not many people receive. Vivienne is among that select few and she's only 9-years-old.
We first met Vivienne last year, fighting to end child slavery one glass of lemonade at a time.
"They said, 'honey, that's a lot of lemonade.'" she said in a 2012 interview.
Vivenne's already donated over $100,000 and now the young girl's lemonade stand has morphed into a bonafide business.
Twitter offers her bottled organic product to employees. And it's now sold in 150 stores, including a market in her Marin County hometown of Fairfax. Five percent of all gross sales goes to her cause.
"We can't keep it on the shelf," said Maura Simmons with the Fairfax Market. "And when people see the truck outside they come in and say, 'is she here?' They want to meet her."
On Thursday the fourth grader took to her Twitter page to share her New York Stock Exchange experience.
A Twitter employee tweeted a pic showing her wearing what she tells me is a custom made tutu posing with Patrick Stewart of Star Trek fame and Cheryl Fiandaca of the Boston Police Department. And here with Twitter co-founder Jack Dorsey.
Vivienne tweeted, "Today I rang the bell for hope and freedom."
Her Twitter account has over 22,000 followers and in Fairfax just about everyone knows the lemonade girl.
"I think it's just a wonderful idea that someone so young can inspire people who are years older than her," Fairfax resident Mariano Abballo said.
Vivienne's company, called "Make a Stand," has an eye-catching marketing tool. Her best friend, 10-year-old Audrey Daniel, didn't get to see her best buddy's bell ringing, but she had this to say, "I think it's really cool that she gets to do that kind of stuff. I think it's just kinda her style of how to do things."
Vivienne's father says Twitter sharing the spotlight with his daughter may turn her moment into a movement.
