Bernd Heinrich

Heinrich was featured in a documentary film series called The Truth About Trees, a production of the James Agee Film Project, which was released in 2015.

In 2011, a 60-minute film, titled An Uncommon Curiosity: at home & in nature with Bernd Heinrich was released. The film follows Bernd Heinrich over the course of a year as he reflects on his past and shares his ideas about nature, science, art, beauty, writing, and running.

In 1983, he set an absolute American record for the 24-hour run of 156 miles, 1388 yards in a track race in Maine. In 1984, he set an absolute American 100 mile record of 12:27:01, again in a track race. One year later, he set the American track record of 7:00:12 for 100 kilometers. In so doing, he became the only American man to hold both the road and track versions of the American record for the same event. His 12:27:01 for 100 miles and 7:00:12 for 100 kilometers still remained, at the end of 2007, the official American track records. In his career, Heinrich set American national records for any age in the standard ultramarathon distances of 100 kilometers, 200 kilometers, 100 miles, and longest distance run in 24 hours. At the end of 2007, Heinrich was inducted into the American Ultrarunning Association's Hall of Fame.

Heinrich then left marathons and moved to ultramarathoning. In 1981, he set several records during a combined 50 mile/100 kilometer road race in Chicago. In the 50 mile race, his second-place finish was a new World record for masters runners. Moreover, he continued running, and in the 100 kilometer race set an absolute American record (i.e., the best of either road or track venues) of 6:38:21 for 100 kilometers. This result was also a World record for masters runners.

Heinrich has won numerous long-distance running events and set a number of open U.S. ultramarathon and masters (age 40 and over) records throughout the 1980s. At the age of 39, Heinrich prefaced his masters career by winning the Golden Gate Marathon outright, with a time of 2:29:16, on a hilly course in San Francisco, California. In 1980, Heinrich ran 2:22:34, his lifetime personal best, in the West Valley Marathon in San Mateo, California, where he placed third and missed qualifying for the 1980 U.S. Olympic Marathon trials by just forty seconds. On April 21, 1980, two days after his 40th birthday, he was the first masters finisher at the Boston Marathon, with a time of 2:25:25, good for 51st place overall.

Heinrich attended Grundschule Trittau (1946–1950) and college at the University of Maine. He then earned his Ph.D in 1970 from the University of California, Los Angeles. In 1971, he accepted a position at the University of California, Berkeley where he became a professor of entomology. Between 1976 and 1977 he was a Guggenheim and Harvard Fellow. In 1980 Heinrich accepted a position as a professor of zoology/biology at the University of Vermont. From 1988 to 1989 he was a von Humboldt Fellow.

Bernd Heinrich (born April 19, 1940 in Bad Polzin, Germany), is a professor emeritus in the biology department at the University of Vermont and is the author of a number of books about nature writing and biology. Heinrich has made major contributions to the study of insect physiology and behavior, as well as bird behavior. In addition to many scientific publications, Heinrich has written over a dozen highly praised books, mostly related to his research examining the physiological, ecological and behavioral adaptations of animals and plants to their physical environments. He has also written books that include more of his personal reflections on nature. He is the son of Ichneumon expert Gerd Heinrich.
