Henri Termeer built Genzyme from a small company of 20 employees into a worldwide life sciences powerhouse, and helped turn Massachusetts into a center for the biotech industry.

He died May 12 after collapsing at his home in Marblehead. He was 71.

Speakers during a memorial service kept returning to how many people benefited from Termeer’s willingness to give back. One beneficiary: the state’s biotechnology industry, which employs more than 60,000 people in Massachusetts, including about 5,000 at the company now called Sanofi Genzyme.
