Howard Hughes was one of the most enigmatic figures of the 20th century—a billionaire industrialist, aviation pioneer, film producer, and ultimately a recluse whose final years were shrouded in mystery. He inherited a fortune, built an empire that spanned airlines and Hollywood, and died in 1976 in circumstances that still raise questions.
His life has been the subject of countless articles, documentaries, and a major Hollywood biopic. Yet many basic facts remain surprisingly obscure: his exact net worth, his height, the car he drove, and even the circumstances of his last days. This article draws on verified sources to separate established facts from lingering uncertainty.
What Was Howard Hughes’s Net Worth?
Hughes was consistently described as one of the richest men in the world, but the exact figure fluctuated dramatically over his lifetime because his holdings changed and his estate was later contested. According to Britannica, he sold his TWA shares in 1966 for more than $500 million alone. At the time of his death, most estimates placed his net worth around $1.5 billion—equivalent to roughly $7 billion today when adjusted for inflation.

What Was Howard Hughes’s Connection to TWA?
Did Howard Hughes Own TWA?
Hughes began buying a stake in Trans World Airlines in 1939 and eventually acquired 78 percent of the company’s stock, according to Britannica. He used his political connections during World War II to secure transatlantic service rights for TWA, making it the only U.S. carrier at the time with both domestic and international routes. Wikipedia notes that this strategic move vaulted TWA into a position of global importance.
What Happened to His TWA Stake?
By the mid-1960s, Hughes’s micromanagement and reclusive behavior had created friction with TWA’s board. In 1966 he sold his entire stake for more than $500 million, as recorded by Britannica. The sale made him even wealthier but also severed his direct involvement with the airline he had helped build.
How Did Hughes Influence Aviation Beyond TWA?
Beyond owning an airline, Hughes was a hands-on aviator and aircraft designer. He founded Hughes Aircraft Company, set world airspeed records, and famously piloted the Spruce Goose—the largest flying boat ever built—in 1947. His obsession with flying and innovation pushed commercial aviation forward, but also contributed to the 1946 crash that left him with lasting pain.
Hughes set a world airspeed record of 352 mph in 1935 flying a Hughes H-1 Racer. The aircraft was designed by his own company.
Did Howard Hughes Have OCD?
What Were His OCD Symptoms?
According to Biography.com, Hughes was thought to have suffered from obsessive-compulsive disorder and a drug problem. The PBS American Experience documentary describes his intense germ fears: he refused to shake hands, wore tissue boxes on his feet, and isolated himself in sealed hotel rooms. The worsening compulsive behavior is closely linked to his retreat from public life after 1950.
Was Hughes Formally Diagnosed?
No formal clinical diagnosis was made during his lifetime. The condition is retrospective, based on extensive documentation from doctors, nurses, and business associates. OCD-UK cites his case as a classic example of severe OCD, noting that he would spend hours washing his hands and refused to touch doorknobs.
How Did OCD Affect His Life and Business?
The disorder shaped every aspect of Hughes’s later years. His paranoia and need for control led to conflict with TWA’s management and contributed to his decision to sell. It also drove his reclusiveness: after going into complete seclusion in 1950, according to Britannica, he rarely appeared in public and conducted business from behind sealed curtains.
It is important to note that OCD was not formally recognized as a diagnostic category in the way it is today. The term “OCD” applied to Hughes is a retrospective interpretation based on documented behaviors, not a medical diagnosis made at the time.
What Was Howard Hughes’s Cause of Death?
When and Where Did He Die?
Howard Hughes died on April 5, 1976, at the age of 70, while aboard a private flight from Acapulco, Mexico, to Houston, Texas. Britannica and Wikipedia both confirm the location as the aircraft itself. Paramedics on the ground found him emaciated and severely dehydrated.
What Did the Autopsy Show?
The immediate cause of death was kidney failure (renal failure), resulting from severe malnutrition and dehydration. Biography.com describes his final decline as the product of years of self-neglect, drug addiction, and the physical toll of his extreme reclusive habits. Some accounts also note that he suffered from bedsores and advanced muscle wasting.
Was His Death Suspicious?
No evidence of foul play has been established. The New York Times obituary reported that the death was consistent with long-term neglect. However, due to the secrecy surrounding his final months, questions about the precise timeline and care he received continue to circulate.
By the time of his death, Hughes weighed only about 93 pounds (42 kg). The PBS documentary notes that by 1966 he had already been in isolation for eight years, and his health only deteriorated further in the following decade.

Why Did Howard Hughes Become a Recluse?
Multiple factors converged to push Hughes into isolation. The 1946 airplane crash left him in chronic pain, and he became reliant on codeine and other narcotics. His obsessive-compulsive behaviors, which had been present since childhood, intensified. He also carried the immense pressure of living up to his father’s legacy and managing a vast, complex business empire.
By 1950, Hughes stopped appearing in public altogether, instead conducting business through intermediaries from darkened hotel suites. His reclusiveness was not merely eccentricity—it was a clinical manifestation of deteriorating mental and physical health. Unlike other famous recluses such as J.D. Salinger or Greta Garbo, Hughes’s seclusion was tied to a documented pattern of paranoia and hygiene obsessions.
His Las Vegas years (1966–1970) were spent in the upper floors of the Desert Inn, with curtains drawn and a small circle of Mormon aides managing his daily needs. The PBS documentary reports that when he arrived in Las Vegas, the only public photos released were from years earlier, illustrating just how long he had been out of view.
