Few individuals in the annals of investment have cast as long and far-reaching a shadow over the corporate world as Carl Icahn. Throughout more than 50 years, he built one of the largest and most intimidating activist-investing firms on the planet. His recipe for success was straightforward: he’d buy a large percentage stake in what he deemed an undervalued business, force managers to boost profits, and sell off stakes once the underlying shares soared in price.
As he went, he turned himself from a modestly funded stock jockey into one of the most powerful and wealthy individuals in America.
Along the way, he shook up corporate boards and launched blockbuster takeovers as he forced the world’s biggest public companies to rethink the way they operated. Where most other investors sit idly by after buying stock, Carl Icahn had no hesitation throwing himself into the management of public companies. He’s worked with companies from sectors as diverse as technology and energy to aviation, cars, casinos, consumer products and real estate. At one time or another during his career – particularly during the heyday of 1980s “greenmail,” – critics nicknamed him a “corporate raider,” but proponents called him an advocate for shareholders rights.
Now the name Carl Icahn continues to loom large over finance in America, its resonance undiminished from its highest point.

Early Life and Education
Born February 16, 1936, in Queens, New York, United States, Carl Celian Icahn came from a middle-class Jewish family that stressed the importance of education and diligence. Both of his parents had careers in teaching and the arts, as his father was both a teacher and a cantor. He received his formal education at Far Rockaway High School, a school that boasted many prominent scientists and business leaders among its alumni.
After graduation from high school, Carl Celian Icahn began studying at Princeton University, majoring in philosophy, a pursuit which taught him to question assumptions and approach problems with a structured and rigorous analysis.
After receiving his degree from Princeton, Icahn spent some time studying at New York University School of Medicine, but it was not a long duration, because after completing a stint in the U.S. Army Reserve, he realized his passion was elsewhere and decided instead to pursue a career in investment finance. This was to be a pivotal moment, leading Carl Celian Icahn to become one of the most renowned investors in the history of the stock market.
Career Journey
Icahn started his career in 1961 as a stockbroker for Dreyfus & Co. The following two years in this company gave him an initial glimpse into investment decisions. Through the 1960s and the first two years of the 70s, he worked for a few brokerage firms learning securities trading, risk arbitrage, and options trading.
Later on, in 1968 he decided to found his own brokerage company Icahn & Co.
With $150,000 in personal and loan assets he used it for an options business and risk arbitrage. The change of his career came around the end of the 70s and the start of the 80s, when he began to initiate hostile takeover procedures. During these years, many corporations appeared to Icahn poorly managed, with stock prices significantly lower than their true worth. Instead of solely taking a portion of the stocks and wait until its value appreciated, he opted to collaborate with the management, pressuring them to adopt significant change or make divestments.
