A Life Without Borders

How a global outlook shaped a lifelong commitment to education and service.

By Eliott Grover

Bill MacArthur ’59, GP’23 has never taken the predictable route. After two years as a Wall Street lawyer, he moved to Tokyo, where he practiced law before helping American Express launch its international banking business back in New York.

In 1977, he and a colleague founded the Trans-Arabian Investment Bank in Bahrain with Saudi partners. While his partner expanded operations across the region, MacArthur connected Middle Eastern clients with U.S. real estate opportunities.

Five years later, sensing another shift ahead, he sold his stake and launched Brooksville Development Corporation. Drawing on relationships forged in Japan, he helped Japanese investors eager to enter the U.S. real estate market.

Over four decades, Brooksville and its Japanese partners developed single-family communities, shopping centers, and the 1,500-room Waldorf/Hilton Hotel complex at Disney World. MacArthur retired in October, closing a chapter on a career defined by bold turns and global reach.

“I’ve had a bit of an unconventional life,” he says.

MacArthur grew up in New England. His parents separated when he was 10, and he stayed with his father, a school administrator. “It was not a particularly happy time,” he recalls. Boarding school soon emerged as the best option.

In seventh grade, he enrolled as a boarder at Hackley School in Tarrytown, NY, where his uncle taught. Two years later, his father joined the faculty as director of admission.

“I was an active child, which is to say I got into trouble fairly frequently,” MacArthur says. “I was putting my uncle and father in an awkward position.” Despite his strong academic and athletic performance, he amassed a long disciplinary record.

Scholarship Opens Doors at Hotchkiss

A lunch with his godfather, Russ Edwards—the beloved Hotchkiss Latin teacher and head of the School’s Dramatic Association—sparked a new direction. MacArthur applied to Hotchkiss and was admitted as a lower mid. Receiving the Lawrence W. Murphy Scholarship enabled him to attend.

“There was no way in God’s green acre I could have gone without a scholarship,” he says.

Lakeville gave the 15-year-old the change of scenery needed, but not the freedom he wanted. “Because of Hackley’s physical position in Tarrytown, it was relatively easy to ‘go over the hill.’ The school was on a hill, and there were local bars and stuff that my friends and I were discovering,” he says. “Hotchkiss seemed a prison compared to that.”

Hotchkiss students could leave campus only one weekend per semester, and MacArthur chafed under the School’s structure. A few days before his upper-mid year started, he decided to return to Hackley.  “I indulged in a lot of foolishness that year,” MacArthur says. “I was spiraling down.”

The following summer brought a reckoning. MacArthur began to think seriously about the direction of his life. In late August, he returned to Hotchkiss on his own and pleaded for readmission as a senior. Despite his checkered record, he had finished in the top 5 percent of his class and lettered in three sports—soccer, swimming, and track. The School agreed to take him back, though there was no space in the dorms. He slept on his godfather’s couch until a bed opened later that fall.

His senior year proved transformative. “I stopped a lot of silly behavior and got serious about my work,” he says. “I owe Hotchkiss an enormous amount. God bless the School. Looking back, I realize what a pivotal moment that was for me––having the nerve to somehow feel that I could talk my way back in. To have that be successful taught me that you could do almost anything if you set your mind to it.” 

That lesson would serve him well throughout his career, where he came to believe that fundamental change should never be avoided when necessary. MacArthur graduated from Yale University and Columbia Law School, but he maintains that the teaching and mentorship he received at Hotchkiss was the best of his education. English instructor Clint Ely left a particularly indelible mark.

“He had this wonderful openness,” MacArthur says. “You really felt that he listened to you. You mattered to him as a person, not just as a student. At that point, I needed a senior male figure in my life, and Ely filled that role.”

After Yale, MacArthur took a teaching job in the Philippines. “I’d grown up in the Northeast and felt I hadn’t experienced much of the world,” he says. The year broadened his perspective and planted seeds that would blossom throughout his life.

His time abroad ignited a lifelong fire. He met his first wife in law school, and their son, Andrew MacArthur P’23, was born while the couple worked as Wall Street lawyers. They quickly became disenchanted with corporate life in New York. When an opportunity arose to join a firm in Tokyo, they leapt.

Two years in Japan were followed by a year-long journey with then 4-year-old Andrew through Southeast Asia, India, and Afghanistan. In Kabul, they bought a used Volkswagen van and spent four months driving and camping through Iran, Iraq, Syria, Lebanon, and Turkey en route to Europe. “A lot of places you wouldn’t take a 4-year-old child today,” MacArthur chuckles. 

The trip was seamless. They sold the van outside the American Express office in Amsterdam, the exact same place the young hippy from whom they had bought it in Kabul had purchased it two years before. 

The young family returned to the States in 1973. Having lost interest in domestic law, MacArthur joined American Express International Banking Corporation—a professional transition that coincided with a personal one. He and his wife had been drifting apart and decided to separate.

At American Express, MacArthur met his second wife, Luz Thoron-MacArthur. Originally from the Philippines, she had worked at the United Nations before moving to Egypt, where her first husband served as president of the American University in Cairo. After his passing, Luz returned to the U.S. and joined American Express. She and MacArthur became a couple in 1976 and have been married for 46 years.

Their relationship is anchored by a shared love of travel and service. MacArthur has visited 103 countries. “I’m horrifically embarrassed to admit that I’m a monolinguist,” he says. “But my wife speaks six languages, so we’re covered.”

Today, they divide their time between Florida, a family compound on the Maine coast, an apartment in New York City—where their children and grandchildren live—and another in Paris. Travel remains constant, often tied to their nonprofit work. Luz co-chairs the Bhutan International Film Festival, and together they support a range of organizations focused on children and education.

After starting Brooksville, MacArthur made a shrewd decision. “I had the good sense to hire three guys who knew more about the business than I did in individual areas,” he says. “That left me with a lot of free time.”

He has spent that time giving back. In the 1990s, while accompanying a friend—then the world’s leading turtle expert—on a turtle hunting trip to Madagascar, he met a Catholic nun named Sister Lucy, who ran an order called the Sisters of the Good Shepherd.

“I met her and she was an extraordinarily charismatic person helping to educate street children in the capital, so I emptied my pockets to her,” MacArthur says. He has supported the order for more than 30 years.

Since then, his philanthropy has taken many forms. Building on his work in Madagascar, MacArthur has helped run a girls’ school in India and a job training program in Tibet, and he has served on nonprofit boards worldwide devoted to education and health. He has also supported a production company whose documentaries on children’s issues have earned international recognition, including an Academy Award. Through it all, he has found deep satisfaction in helping others gain the opportunities that once changed his own life.

MacArthur Fellowship Gives Gap Year to Bearcats

Two years ago, MacArthur returned to Hotchkiss for the graduation of his granddaughter, Aislinn MacArthur ’23. The following day, his son Andrew invited him to join a meeting with Head of School Craig W. Bradley.

“My wife was in the car, and I was a little puzzled,” MacArthur recalls.

Bradley described a new scholarship program Andrew was helping to launch—one that would fund overseas experiences for young alumni.

“What a great program,” MacArthur said.

“I don’t think you understand,” Bradley replied. “Andrew is naming this after you.”

MacArthur burst into tears. He quickly composed himself and embraced his son.

“I was deeply touched by my son’s generosity and thoughtfulness,” he says. “It was such a wonderful thing, given what my interests were and how important that time abroad was for me going forward. Andrew recognizes the value of a gap year abroad. He spent 10 years in Asia after graduation, working for The Wall Street Journal, arranging conferences and establishing print sites throughout the continent. That period abroad of independent activity also formed the basis of an exceptionally successful entrepreneurial career in real estate.”

The MacArthur Fellowship, the only one of its kind among peer independent schools, awards three graduating seniors or recent alumni a grant to fully fund an international gap year. Fellows design their own projects around service, internships, learning, cultural immersion, adventure, or other pursuits.

“I did that on a shoestring,” MacArthur says of his year in the Philippines and ensuing trip home. “If students can map out a year and do all sorts of different things without worrying about earning money along the way, that’s a fantastic opportunity.”

He speaks with quiet pride and gratitude as he reflects on his son’s gesture. For MacArthur—who has stayed connected to Hotchkiss through his class reunion committee, ongoing support of The Hotchkiss Fund, and participation in an online forum with his classmates—the fellowship is more than a tribute. It’s a continuation of his heartfelt belief that time spent exploring the world can open minds, deepen empathy, and shape a person for life. 

And, importantly, it maintains his ongoing connection to Hotchkiss.
