Herbert "Herbie" Wertheim is an American billionaire investor, optometrist, inventor, entrepreneur, and philanthropist who has a net worth of $5 billion.

Herbie Wertheim built one of the more unusual fortunes in American business history. Rather than becoming rich by taking a company public, running a hedge fund, or founding a technology giant, he accumulated the majority of his wealth by investing his own money in publicly traded stocks for more than half a century.

Wertheim founded the optical-products company Brain Power Inc. in 1970 and turned it into a highly profitable manufacturer of lens tints and related technologies. But instead of aggressively expanding the company, he used its profits to buy stocks. Among his most successful investments were early positions in Apple and Microsoft and a roughly $5 million investment in aerospace-parts manufacturer Heico that eventually became worth hundreds of millions of dollars.

Wertheim became known for buying companies he believed had valuable technology and intellectual property, holding those investments for decades, and generally avoiding frequent trading. His enormous portfolio was managed largely through ordinary brokerage accounts at Fidelity and Schwab.

His wealth has financed an extensive philanthropic career as well as an extraordinary collection of homes and automobiles. In 2025, Wertheim paid $26 million for a one-of-one Ferrari Daytona SP3 at a charity auction. The following year, he spent $40 million for "Chassis 0" of the Ferrari Luce, the first production example of Ferrari's first electric vehicle.

Herbert Wertheim was born on May 23, 1939, in Philadelphia, Pennsylvania. His parents were Jewish immigrants who had fled Nazi Germany. In 1945, the family moved to Hollywood, Florida, where they lived in an apartment above the family's bakery.

Wertheim struggled academically because of dyslexia at a time when learning disabilities were poorly understood. He later recalled being treated as though he was unintelligent and being forced to wear a dunce cap in school.

His home life was also difficult. Wertheim has described his father as abusive, and as a teenager he periodically ran away. He spent time hunting and fishing in the Everglades with members of the Seminole community and earned money selling frog legs and other game. He also hitchhiked around Florida picking oranges and grapefruits.

At 16, Wertheim found himself before a judge because of truancy. The judge offered him a choice between state reform school and military service. Wertheim chose the Navy and enlisted at 17 in 1956.

The Navy proved transformative. Aptitude testing showed that Wertheim excelled in areas such as mechanics and organization, giving him confidence that had been largely absent during his school years. He studied physics and chemistry and worked in naval aviation.

It was also during his Navy years that Wertheim began investing. At 18, he used money from his military stipend to buy stock in Lear Jet, attracted by the company's aviation technology and inventions.

After leaving the Navy, Wertheim briefly sold encyclopedias door-to-door before attending Brevard Community College and the University of Florida, where he studied engineering but did not graduate.

While taking classes, he worked for NASA during the early years of the space program in a division involved with improving instrumentation for manned spaceflight. His engineering work helped develop his interest in optics and the ways instruments could improve human vision.

In 1963, Wertheim received a scholarship to attend the Southern College of Optometry in Memphis. After graduating, he opened an optometry practice in South Florida. His patients were largely working-class, and he later recalled that some occasionally paid him with produce such as mangoes and avocados.

Wertheim continued experimenting and inventing after work. In 1969, he developed a tint for plastic eyeglass lenses designed to absorb and filter ultraviolet light. He initially licensed the technology for $22,000, but problems with the licensing arrangement prevented him from receiving the royalties he expected.

In 1970, Wertheim founded Brain Power Inc., or BPI, initially as a technology consulting business. He soon began developing optical tints, dyes, laboratory equipment, cleaners, and other products for opticians, optometrists, and ophthalmologists.

One of his early breakthroughs was a chemical neutralizer that could restore tinted plastic lenses to their original clear condition. Before products like Wertheim's neutralizer, optical businesses often needed to maintain inventories of lenses in numerous colors or throw away lenses that had been incorrectly tinted.

BPI eventually grew into one of the world's largest manufacturers of optical tints, supplying products to major companies including Bausch & Lomb, Zeiss, and Polaroid. The company accumulated more than 100 patents and copyrights connected to optical technology.

What is particularly remarkable about BPI is how deliberately small Wertheim kept the operation. In 2019, it was reported that the company employed only 49 people and generated around $25 million in annual revenue and approximately $10 million in net income.

For many entrepreneurs, that level of profitability would have been a reason to expand aggressively. Wertheim had a different objective. He wanted the business to provide income and freedom while leaving him time to invest.

It was Wertheim's investment portfolio, rather than BPI itself, that ultimately made him a multibillionaire.

He regularly directed a portion of his earnings and the profits from Brain Power into stocks. His approach combined extremely long holding periods with an emphasis on technology, industrial companies, intellectual property, and dividends.

Wertheim bought Microsoft shares during the company's 1986 IPO. By 2019, his original Microsoft investment was worth more than $160 million.

He also invested in Apple during its 1980 IPO and purchased additional shares when Apple struggled during the 1990s. By 2019, he owned roughly 1.25 million Apple shares that were valued at about $195 million.

Instead of focusing primarily on quarterly earnings or traditional Wall Street valuation metrics, Wertheim became known for studying patents. He reportedly devoted two six-hour sessions every week to examining technical materials and intellectual property, believing patents could reveal a company's long-term potential before that value showed up in its financial statements.

His investments over the years included IBM, Intel, 3M, General Electric, Google, BP, Bank of America, and many others.

Wertheim generally preferred buying and holding rather than trading. When a stock he strongly believed in declined, he was often willing to buy more. He also favored dividend-paying companies, using the cash generated by dividends for new investments or living expenses.

Wertheim's greatest investment may have been Heico, an aerospace and electronics company headquartered in Hollywood, Florida.

He became friendly with businessman Laurans "Larry" Mendelson during the 1970s. When the Mendelson family became interested in taking control of the struggling aerospace-parts manufacturer, Wertheim used his aviation and engineering knowledge to help analyze the company.

Wertheim began buying Heico shares when the stock traded for as little as 33 cents. He ultimately invested around $5 million.

Under the Mendelson family, Heico expanded its business supplying FAA-approved replacement parts for aircraft and developed a powerful niche in the aerospace industry. Over the following decades, the company's revenue and profits compounded at extraordinary rates.

By 2019, Wertheim's original $5 million investment had grown to more than $800 million, making him Heico's largest individual shareholder.

Wertheim's investment career was not without major losses.

In 1982, he suffered a devastating margin call during the period when Federal Reserve Chairman Paul Volcker dramatically raised interest rates to fight inflation. According to Wertheim, the episode cost him $50 million.

The loss taught him a lasting lesson about excessive leverage.

He also made an unsuccessful investment in BlackBerry after betting on a turnaround that failed to materialize. Although Wertheim usually favored extremely long holding periods, he said he would generally sell when an investment moved roughly 25% against him and his original thesis no longer appeared to be working.

Wertheim has devoted hundreds of millions of dollars to education, medicine, research, and other charitable causes.

He and his former wife, Nicole, became major benefactors of Florida's public universities. Institutions bearing the Wertheim name include the Herbert Wertheim College of Medicine at Florida International University, the Herbert Wertheim College of Engineering at the University of Florida, the Herbert Wertheim College of Business at Florida State University, the Herbert Wertheim School of Public Health and Human Longevity Science at UC San Diego, and the Herbert Wertheim School of Optometry & Vision Science at the University of California, Berkeley.

By 2026, Wertheim had contributed more than $300 million to higher education in Florida alone.

In May 2026, he announced a $100 million donation to Baptist Health South Florida, the largest single philanthropic gift in the organization's history. The donation supported cancer treatment, research, prevention, and education, and the Miami Cancer Institute was renamed the Baptist Health Herbert Wertheim Cancer Institute.

Wertheim is also a signer of the Giving Pledge, committing the majority of his fortune to philanthropy.

Wertheim has attracted increasing attention for his appetite for extraordinarily rare Ferraris.

At Monterey Car Week in August 2025, he paid $26 million for a one-of-one Ferrari Daytona SP3 "Tailor Made." The car was an additional example produced beyond the normal 599-car Daytona SP3 production run and was informally known as "599+1." The proceeds benefited the Ferrari Foundation.

One year later, Wertheim returned to the same RM Sotheby's Monterey auction and paid $40 million for the Ferrari Luce "Chassis 0."

The Luce is Ferrari's first electric vehicle, and Chassis 0 is the first production example. The bespoke Tailor Made car has an estimated MSRP of $1.1 million, meaning Wertheim paid more than 36 times that amount. At $40 million, it became the most expensive new automobile ever sold at auction.

Once again, the buyer's premium was waived and the proceeds went to the Ferrari Foundation for educational initiatives.

Wertheim's investment success has allowed him to assemble a substantial collection of luxury properties. His holdings include a $16 million oceanfront residence in Coral Gables, Florida, a 90-acre ranch near Vail, Colorado, a four-story home overlooking the Thames in London, and two estates in Southern California.

He also owned two residences aboard "The World," the luxury residential ship whose owners travel continuously around the globe.

Wertheim was married to Nicole Wertheim for more than five decades. Together they built both Brain Power and the family foundation and became major philanthropists. Their marriage eventually ended in divorce. Nicole Wertheim died in 2026.

Despite becoming a multibillionaire, Wertheim has remained closely identified with the investment strategy that created his fortune: research businesses carefully, buy companies with technology he believes will matter decades into the future, and hold onto the winners for as long as possible.
