Texas Oil Billionaire William ‘Tex' Moncrief Jr. Dead at 101

William Alvin Moncrief Jr., a Texas wildcatter who helped build a father-son venture into an oil and gas empire over more than 70 years in the industry, has died. He was 101.

A spokeswoman for Moncrief Oil confirmed his death to The Associated Press Wednesday but could not immediately provide further details.

Moncrief, who went by the nickname “Tex,” was born in Arkansas in 1920 on his family’s kitchen table, according to Texas Monthly. His father, William Alvin “Monty” Moncrief, was among the early wildcatters to drill for oil in East Texas.

The younger Moncrief spent his life building on that tradition, acquiring a fortune that earned him a reputation as a generous philanthropist but also attracted scrutiny from tax authorities.

At the age of 10, Moncrief witnessed his father open a “gusher” oil well in Greggton, 128 miles east of Dallas. People who gathered to watch the drilling and were initially disappointed when the well pushed up only muddy water, the younger Moncrief told the Longview News-Journal last year.

But then “it shot out about 90 to 100 feet,” he recalled. “When it shot out 100 feet, it made solid oil.”

As a young man, Moncrief considered quitting school to pursue golf professionally. But his father talked him out of it and he graduated from the University of Texas in 1942 with a degree in petroleum engineering.

After the United States entered World War II, Moncrief enlisted and served as a naval officer in the Pacific. Upon returning to Texas, he went into business with his father and the pair acquired major oil and gas prospects across the country.

Moncrief ranks among a generation of tycoons who built the Texas oil and gas industry, including Sid Richardson, Cary Maguire and Ed Cox, according to Bruce Bullock, director of the Maguire Energy Institute at Southern Methodist University in Dallas. Their names are also now on civic and medical institutions in the Dallas-Forth Worth area thanks to their philanthropy.

“With Tex as well as the other kind of legendary wildcatters, they were pioneers in the sense that they really didn’t believe in large corporations. They believed in smaller-leaning, sole proprietorships, if you will, which meant they took an awful lot of risk,” Bullock told the AP on Wednesday. “There just aren’t people around like that anymore.”

Forbes magazine named Moncrief to its billionaires list in 2006 and listed his net worth as $1 billion in 2014, writing that the biggest find of his career came four years earlier with the discovery of the deep-water gas reserves off the coast of Louisiana that became known as the “Davy Jones” field.

In 1994, Moncrief’s wealth attracted the attention of tax authorities. Internal Revenue Service agents raided his Fort Worth offices and later accused his family and company of bilking the government out of more than $100 million in taxes. Moncrief eventually pleaded no contest to a tax suit, paying the IRS $23 million but decrying the agency’s aggressive tactics.

Moncrief was a major donor to Texas Christian University, University of Texas, and the UT Southwestern Medical Center, where a Fort Worth medical complex and cancer center are named for him. He also served on the University of Texas System board of regents.

State Rep. Charlie Geren, a Fort Worth Republican, said Moncrief’s philanthropy improved many lives.

“He was an incredibly generous man and a real legend in the Texas oil and gas industry,” Geren said.
