158. Jack Dorsey
Jack Dorsey, (born November 19, 1976, St. Louis, Missouri, U.S.) American Web developer and entrepreneur who, with Evan Williams and Christopher Stone, cofounded (2006) the online microblogging service Twitter.
As a teenager, Dorsey created taxi-dispatching software that was adopted by taxicab companies. He attended New York University before moving (1999) to San Francisco, where he set up a company that used the Internet to handle the dispatching of couriers and emergency vehicles as well as taxis. In 2000 he first considered using text and instant messaging (based on the principles of dispatch software) as a way of keeping in touch with friends. Six years later he approached Williams and Stone with his idea; together they developed a prototype of what would become the Twitter platform. Dorsey posted the first Twitter message on March 21, 2006. The service, which allowed users to send messages no longer than 140 characters, quickly became a popular social networking hub as well as a mainstream form of communication. Dorsey served as CEO until October 2008, when he became chairman of the board. In that capacity, he was involved with Twitter’s initial public offering (2013), which raised $1.8 billion.
In 2009 Dorsey cofounded and became CEO of Square, a mobile-payments venture that offered devices and software to facilitate credit-card transactions. It launched in 2010 and by 2012 had more than two million users. Square initially was available only in North America, but it expanded to overseas markets in 2013, when its services became available in Japan. That year Dorsey also became a member of Disney Company’s board of directors. In October 2015 he once again became CEO at Twitter while also remaining as Square’s CEO.

157. Alicia Silverstone
Alicia Silverstone (born October 4, 1976) is an American actress, producer, author, and activist. Silverstone made her film debut in The Crush, earning the 1994 MTV Movie Award for Best Breakthrough Performance, and gained further prominence as a teen idol when she appeared in three music videos for the band Aerosmith. She starred in the 1995 hit Clueless (which earned her a multimillion-dollar deal with Columbia) and in the big-budget 1997 film Batman & Robin, in which she played Batgirl. She has continued to act in film and television and on stage. For her role in the short-lived drama comedy Miss Match, Silverstone received a Golden Globe nomination for Best Actress – Television Series Musical or Comedy. A vegan, Silverstone endorsed PETA activities and published a book titled The Kind Diet.
Silverstone was born in San Francisco, California, the daughter of Deirdre "Didi" (née Radford), a Scottish former Pan Am flight attendant, and Monty Silverstone, an English real estate agent. She grew up in Hillsborough, California. Her father was born to a Jewish family and her mother converted to Conservative Judaism before marriage; Silverstone had a Bat Mitzvah ceremony. Silverstone began modeling when she was six years old, and was subsequently cast in television commercials, the first being for Domino's Pizza. She attended Crocker Middle School and then San Mateo High School.
Silverstone has won several awards for her film performances. She received multiple MTV Movie Awards and a Young Artist Award for The Crush. For Clueless, she received multiple MTV Movie Awards and a Young Artist Award once again, plus awards from Blockbuster Entertainment Award, Kids' Choice Awards, National Board of Review, and an American Comedy Award.
Her first credited acting role was in The Wonder Years, starring Fred Savage, in the episode entitled "Road Test", as Savage's character's high school "dream girl". Silverstone then won a leading part in the 1993 film The Crush, playing a teenage girl who sets out to ruin an older man after he spurns her affections; she won two awards at the 1994 MTV Movie Awards for the role—Best Breakthrough Performance and Best Villain. Silverstone became legally emancipated at the age of 15 in order to work the hours required for the shooting schedule of the film. Silverstone made some television movies in her early career including Torch Song, Cool and the Crazy and Scattered Dreams. In addition, Silverstone was almost chosen to play the lead role of Angela Chase in the critically acclaimed cult television series My So-Called Life before production of the pilot episode began. The role eventually went to Claire Danes.
After seeing her in The Crush, Marty Callner decided Silverstone would be perfect for a role in a music video he was directing for the band Aerosmith, called "Cryin'"; she was subsequently cast in two more videos, "Amazing" and "Crazy." These were hugely successful for both the band and Silverstone, making her a household name (and also gaining her the nickname, "the Aerosmith chick"). After seeing Silverstone in the three videos, filmmaker Amy Heckerling decided to cast her in Clueless.
Clueless became a hit and critical darling during the summer of 1995. As a result, she signed a deal with Columbia-TriStar valued between $8 and $10 million. As part of the package, she got a three-year first look deal for her own production company, First Kiss Productions. Silverstone also won "Best Female Performance" and "Most Desirable Female" at the 1996 MTV Movie Awards for her performance in the film. In the same year Silverstone starred in the erotic thriller, The Babysitter, film adaptation of the novel by Dean Koontz, Hideaway, and the French drama about Americans, New World.
Silverstone's next role was as Batgirl in Batman & Robin, and while it was not a critical success, the film grossed $238,207,122 worldwide. Silverstone's turn as Batgirl was not well received, and won her a Razzie Award for Worst Supporting Actress. She also, however, won a Blimp Award at the Kid's Choice Awards for the role. Also released in 1997 was Excess Baggage, the first movie by Silverstone's production, Silverstone starred in the Saturn Award-nominated romance/comedy film Blast from the Past which also stars Brendan Fraser, Christopher Walken and Sissy Spacek.
In 2000, Silverstone appeared in Kenneth Branagh's film adaptation of the William Shakespeare's Love's Labour's Lost, in which she was required to sing and dance. In 2001, Silverstone provided the voice of Sharon Spitz, the lead character in the Canadian animated television Braceface. During this time, she also appeared in the films Global Heresy and Scorched. In 2002, she made her Broadway debut alongside Kathleen Turner and Jason Biggs in The Graduate. After removing herself from the public eye for a few years, she resurfaced in the short-lived 2003 NBC television series Miss Match, which was canceled after 11 episodes. Silverstone later acknowledged that she hates the trappings of fame, saying, "Fame is not anything I wish on anyone. You start acting because you love it. Then success arrives, and suddenly you're on show".

Silverstone has two older siblings, a half-sister from her father's previous marriage named Kezi Silverstone and a brother named David Silverstone. She married her longtime boyfriend, rock musician Christopher Jarecki, in a beachfront ceremony at Lake Tahoe on June 11, 2005. After meeting outside a movie theater in 1997, the couple dated for eight years prior to their marriage. They got engaged about a year before their marriage, and Jarecki presented Silverstone with an engagement ring that had belonged to his grandmother. They live in an eco-friendly Los Angeles house, complete with solar panels and an organic vegetable garden. Silverstone bought the house, shared with a "menagerie of rescued dogs", in 1996.
In 2009, Silverstone released The Kind Diet, a guide to vegan nutrition, and launched its associated website The Kind Life.

She became a vegan in 1998 after attending an animal rights meeting, saying "I realized that I was the problem … I was an animal lover who was eating animals." She has stated she struggled with childhood vegetarianism, stating "at eight years old it's hard to stick to your guns – and so through the years I was always starting and stopping trying to be a vegetarian."
