Summary

A plumber's son on Long Island, he dug ditches, caddied, and worked as a butcher's assistant to get through Bucknell on a mortgage his parents took out.

A Wall Street career led him to found his own bank, Invemed. In 1978 he raised the $2 million that financed The Home Depot for Bernie Marcus and Arthur Blank, keeping a 5 percent stake — nearly all his fortune traces back to it.

How it happened

iA plumber's son on Long Island

Born September 16, 1935, in Roslyn Heights, on Long Island. His father worked as a plumber, paid by the hour and laid off at the end of each job, and is also described in a published profile as having struggled with manic depression; his mother worked in the cafeteria of the public school across the street from their house. Both parents were themselves children of Italian immigrants, so the family had already been in the US for at least a generation by the time he was born. It was a large extended family on a tight budget, with no money to spare and nothing to transfer.

iiDitch digger, caddy, butcher's assistant

His high school principal advised against sending him to college at all. His parents mortgaged their house anyway to send him to Bucknell University, and he worked through it himself — as a ditch digger, a golf caddy, and a butcher's assistant — to cover what the mortgage didn't. He finished a bachelor's degree in economics in three and a half years.

iiiNight school and Wall Street

He went to work at the Equitable Life Assurance Society in 1957 while studying for an MBA at night at NYU's business school, completing it in 1960 (NYU later named its part-time MBA program for him). After military service, he joined the Wall Street firm R.W. Pressprich & Co. in 1961, rising to executive vice president and then, by 1969, president.

ivThe Perot IPO

At Pressprich he arranged the 1968 initial public offering of Ross Perot's Electronic Data Systems, a deal that made him a name on Wall Street as a financier who could get something done — well before Home Depot existed as an idea.

vFounding Invemed

In 1974 he founded his own investment bank, Invemed Associates, built on the Wall Street relationships and reputation he had spent more than a decade assembling rather than on family money or an inherited client book.

viBacking Marcus and Blank
Turning point

In 1978, after Bernard Marcus was fired as CEO of the Handy Dan home-improvement chain — a company Langone knew as an investor — and teamed up with Arthur Blank, Langone used Invemed to put together roughly $2 million in outside financing so the two could open the first Home Depot stores. Outside investors took half the new company for that $2 million; Langone kept 5 percent for himself for assembling the group. That stake, compounding with Home Depot's growth into one of the world's largest retailers, is the foundation of nearly all his later wealth.

viiChairing NYSE pay, then the Grasso fight

He chaired the New York Stock Exchange's compensation committee from 1999 to 2003, and in that role helped set the roughly $139.5 million pay package awarded to then-NYSE chairman Richard Grasso. New York Attorney General Eliot Spitzer sued over the package in 2004 and named Langone alongside Grasso, alleging the committee hadn't been given full information about the package's size. A New York court dismissed the claims against Langone in 2008, after the exchange's conversion from a nonprofit to a for-profit company changed the legal basis for the suit. Langone fought the case publicly for years and maintained he had done nothing wrong; no judgment or penalty was ever entered against him.

viiiGiving it away, loudly

He and his wife, Elaine, gave more than $200 million to NYU's medical school and hospital system, which was renamed NYU Langone Health in recognition, and pledged another $100 million in 2018 toward free tuition for its medical students. He has also given tens of millions to his alma mater, Bucknell. In 2018 he published a memoir, "I Love Capitalism! An American Story," and has long been an outspoken, frequently quoted Republican donor and commentator on the record against single-payer health care and free college tuition.

ixWhere it stands

Forbes put his personal net worth at about $9.9 billion as of October 1, 2026, almost all of it traceable to his Home Depot stake and Invemed. He remained active in business and public commentary into his nineties.

Can you replicate their success?

Partly

The credential route he used is still open: a self- and family-financed bachelor's degree followed by a part-time MBA earned while working full time remains a real door into finance, and night-MBA programs modeled on exactly that path still exist (NYU's is now named for him). Much harder to repeat is the specific Wall Street window he worked in, where a personal reputation built one relationship and one deal at a time — a well-regarded IPO here, a board seat there — could translate into assembling millions in outside capital for a complete outsider with an unproven retail idea. Big-box home improvement is now a mature, saturated category rather than a wide-open one, and the kind of financier access Langone had, where investors return his call on the strength of his own name, is far harder for a newcomer to build today in a more institutionalized, credential-gated venture and private-equity world.

Required conditions
1 A funded, even if self- or family-financed, college and graduate credential as the door into Wall Street
2 Years spent building a personal dealmaking reputation inside an established firm before striking out alone
3 A pre-existing investor relationship that puts you in the room when a founder needs backing
4 Access to outside capital willing to bet on an unproven retail format in a still-open market

Structural context

founder lens · venture capital

The cost-of-failure score comes from this person's own money and circumstances. But who they were in America carried its own weight, the same way their household or income did, and it shaped how hard the path was just as much. That part isn't in the cost-of-failure number. It's here instead.
