Michael Hawley, a computer programmer, professor, musician, speechwriter and impresario who helped lay the intellectual groundwork for what is now called the Internet of Things, died Wednesday at his home Cambridge, Massachusetts. He was 58.

The cause was colon cancer, said his father, George Hawley.

Hawley began his career as a video game programmer at Lucasfilm, the company created by “Star Wars” director George Lucas. He spent his past 15 years curating the Entertainment Gathering, or EG, a conference dedicated to new ideas.

In between, he worked at NeXT, the influential computer company founded by Steve Jobs after he left Apple in the mid-1980s, and spent nine years as a professor at the Massachusetts Institute of Technology Media Lab, a seminal effort to push science and technology into art and other disciplines. He was known as a scholar whose ideas, skills and friendships spanned an unusually wide range of fields, from mountain climbing to watchmaking.

Hawley lived with both Jobs and artificial intelligence pioneer Marvin Minsky, published the world’s largest book, won first prize in an international competition of amateur pianists, played alongside cellist Yo-Yo Ma at the wedding of celebrity scientist Bill Nye, joined one of the first scientific expeditions to Mount Everest, and wrote commencement speeches for Jobs and Google co-founder Larry Page.

Two of Hawley’s Media Lab projects — Things That Think and Toys of Tomorrow — anticipated the Internet of Things movement, which aims to weave digital technology into everything from cars to televisions to home lighting systems. Led by companies like Amazon, Google, Intel and Microsoft, the movement is now a $248 billion market, according to market research firm Statista.

Hawley developed “a pattern of ideas that emerged long before the Internet of Things,” Nicholas Negroponte, founder of the Media Lab, said in an email.

“I would call that pattern not artificial intelligence, but intelligence in the artificial,” he wrote.

Mark Seiden, an independent computer security consultant who met Hawley in the early 1980s when they were both working at IRCAM, a music lab in Paris, and eventually hired him at Lucasfilm, compared Hawley’s exploits to those of George Plimpton, the writer whose participatory kind of journalism had him masquerading as a boxer, a professional football player, a circus performer and a stand-up comedian.

“Plimpton was a famous dilettante,” Seiden said. “Mike was just as a diverse as Plimpton — except he wasn’t a dilettante.”

Michael Jerome Hawley was born Nov. 18, 1961, at the Camp Pendleton Marine Corps base near Oceanside, California, to Mary Kay (Dixon) and George Hawley, and grew up in New Providence, New Jersey, about 17 miles west of Newark. While still in high school, he interned at Bell Labs, where his father was an electrical engineer. He also underwent years of formal training as a pianist and went on to study both music and computer science as an undergraduate at Yale, earning degrees in each.

After meeting Jobs in the lobby of Lucasfilm in the early 1980s, Hawley shared a house with him and spent six years at NeXT, which aimed to build a new kind of personal computer. For this machine Hawley built one of the first digital libraries. A friend of his had worked on a new edition of “The Complete Works of Shakespeare” at Oxford University Press, so Hawley and Jobs flew to England to negotiate a deal for the digital files, offering $2,000 upfront and 74 cents for each personal computer sold.

When the NeXT machine was launched, Hawley added a dictionary, a thesaurus and a book of quotations — all now standard online fare.

In 2005, he helped write Jobs’ Stanford University commencement speech (“Stay hungry, stay foolish” was one of its much-quoted lines), which did much to define the Apple founder as an international celebrity in his last decade. Four years later, after meeting Page on a boat ride across San Francisco Bay, Hawley repeated the trick, writing the commencement speech that Page delivered at the University of Michigan.

After he joined the brand-new MIT Media Lab as a graduate student in 1985, Hawley lived in Minsky’s attic, and after finishing his doctorate he stayed on at MIT as a professor.

In 1998, he served as the scientific director on an expedition to Mount Everest. Four years later, he tied for first place in the prestigious Van Cliburn amateur piano competition in Fort Worth, Texas, playing his own arrangement of a suite of pieces from “West Side Story.” (His selection of Broadway show tunes proved a controversial choice.)

As the director of special projects at MIT, Hawley published “Bhutan: A Visual Odyssey Across the Himalayan Kingdom” in 2003, drawing on his experiences and photographs spanning four visits to Bhutan over a decade and a half. Measuring 5 by 7 feet and weighing more than 130 pounds, it was certified by Guinness World Records at the time as the world’s largest book.

“Michael was always finding some cool new idea,” Seiden said. “And then he would actually do it.”

Hawley and his wife, Nina You, were married at Kyichu Lhakhang, a seventh-century Bhutanese temple, and lived in a 193-year-old church in East Cambridge, where he kept three pianos, including a Steinway. She and his father survive him, as do a son, Tycho; a daughter, Choki Lhamo; and two brothers, Stephen and Patrick.
