Replace some deteriorating willow trees that have been identified as "hazard trees" and could pose a threat to path users during windy days. [...]
Brown says the difficult decision to replace trees — for both safety and path re-grading purposes — was made to ensure long-term protection of path users, and the environmentally and technologically sensitive areas nearby. Most of the trees that will be replaced were planted by the university in the 1980s and are already showing signs of decline.
The path was called University Drive in this 1915 photo from vfm4's 1915, Madison, Wisconsin Set. It was renamed as a memorial to Howard Temin after the untimely 1994 death the University of Wisconsin's molecular geneticist and Nobel Laureate (Medicine, 1975) who had not even been born when the older photo was taken. Howard Temin shared the Prize in Physiology or Medicine for the discovery of reverse transcriptase. A strong opponent of cigarette smoking, he died of lung cancer at the age of 59, although he had never smoked.
