Robert “Bob” Duggan is an American entrepreneur, biotech executive, and philanthropist. He is currently the CEO of Summit Therapeutics, chairman of the board for Pulse Biosciences, and CEO of Duggan Investments.
Duggan is known for his dedication to positive change and education, and his recent investments are focused on finding breakthrough solutions to complex diseases.
His career has been defined by entrepreneurial ventures. Duggan grew up in a lower middle-class family in San Jose, California, where he was the third of five children. As a teenager, he mowed lawns to earn money for college.
He spent four years studying economics at the University of California, Santa Barbara, and another two studying business administration at UCLA, but he did not ultimately earn a degree. While at UCSB, he connected with a professor, Herbert C. Kay, who became a mentor and provided Duggan with a three-year apprenticeship.
Duggan then began a series of venture capital pursuits, including Sunset Designs which produced the successful Jiffy Stitchery embroidery kits, and Paradise Bakery, which pioneered the distribution of fresh baked goods, garnering corporate clients like McDonald’s, Kentucky Fried Chicken, and Disney World.
After the success of previous ventures, Duggan went on to launch or invest in a variety of businesses and startups, particularly in the areas of technology and medicine. He has been instrumental in the turnaround of several failing companies, perhaps most notably during his time as CEO of Pharmacyclics, which he sold to AbbVie for $21 billion in 2015. Duggan rallied shares from $0.57 each in 2009 to over $260 just seven years later. The company’s good fortune was primarily due to the success of its drug, Imbruvica, a treatment for chronic lymphocytic leukemia.
Duggan makes significant contributions to causes that align with his mission of doing good, including human rights, education, social betterment, and drug rehabilitation. Duggan is a member of the Church of Scientology and has been noted as its largest donor, in excess of $360 million.
He is a longtime trustee of the UC Santa Barbara Foundation, where he has funded several academic chairs as well as athletic scholarships. Some of Duggan’s honors include receiving a U.S. Congressman’s Medal of Merit, being named a Knight of the Legion D’Honor by French President Jacques Chirac, and being included on Forbes’ Billionaires list.
