James Joseph Cramer, born on February 10, 1955, in Wyndmoor, Pennsylvania, is an American television personality, author, and former hedge fund manager renowned for his energetic style and market insights. Raised in a Jewish family in the Philadelphia suburbs, Cramer developed an early interest in finance, influenced by his father's involvement in the Philadelphia Stock Exchange. He pursued higher education at Harvard College, graduating with a Bachelor of Arts in American Government in 1977, followed by a Juris Doctor from Harvard Law School in 1981. After law school, Cramer briefly worked as a lawyer but quickly transitioned to finance, joining Goldman Sachs as a stockbroker in the risk arbitrage department from 1981 to 1984.

Cramer's career in finance accelerated when he founded Cramer & Co., a hedge fund, in 1987, which he later renamed Cramer Berkowitz & Co. The fund achieved significant success, posting average annual returns of 24% after fees from 1987 to 2000. In 1996, he co-founded TheStreet.com, an online financial media company, where he served as a columnist until 2021. Transitioning to broadcasting, Cramer co-hosted CNBC's Kudlow & Cramer from 2002 to 2005 and launched his flagship show, Mad Money with Jim Cramer, in 2005, which became a staple for retail investors with its boisterous advice and theatrical presentations. He also anchors Squawk on the Street and has appeared as a contributor on other programs.

Beyond television, Cramer has authored several bestselling books on investing, including Confessions of a Street Addict (2002), Jim Cramer's Real Money: Sane Investing in an Insane World (2005), and Stay Mad (2023). His influence extends to social media and philanthropy, though he has faced criticism for potential conflicts of interest between his media role and past financial ties. Cramer's net worth is estimated in the tens of millions, derived from his hedge fund, media career, and book sales, solidifying his status as a key figure in financial media and investor education.
