Milton, Norfolk County, Massachusetts
Marker Inscription
The Blue Hill Observatory was founded by MIT graduate Abbott Lawrence Rotch as a private scientific station for the study of weather and the atmosphere. The first weather observations were made on february 1, 1885 and they have continued uninterrupted to the present day. This makes it the oldest continuously operating weather station in the nation and a benchmark for world climatology. Owned and operated by Harward university for 60 years , Blue Hill Observatory, in conjunction with the Massachusetts department of conservation and recreation, is now a not-for-profit climate station, educational center, and museum. The observatory and gift shop are open to the public weekends and by appointment.
The Story
Founded by MIT graduate Abbott Lawrence Rotch as a private scientific station, the Blue Hill Observatory took its first weather observations on February 1, 1885 â a record that has continued unbroken ever since. That makes it the oldest continuously operating weather station in the nation and a benchmark for global climate study. Once run by Harvard for six decades, it now serves as a nonprofit climate station, museum, and educational center.
Why it matters
Its unbroken 140-year record is a priceless scientific resource, making this hilltop a cornerstone of American meteorology and climate science.

Commemoration of the 50th Anniversary of The Smoot
Cambridge, MA
In October 1958, MIT fraternity pledge Oliver R. Smoot was laid end-over-end 364 times to measure the Harvard Bridge over the Charles River, giving the world a delightfully absurd unit: the Smoot, equal to his own five-foot-seven height. The bridge came out to '364.4 Smoots plus one ear,' and the paint marks his Lambda Chi Alpha brothers laid down have been faithfully repainted by generations of pledges ever since. This plaque, dedicated to Smoot, MIT Class of 1962, marks the 50th anniversary of a prank that outlived its pranksters' expectations.
Prof. John Winthrop's Home
Cambridge, MA
John Winthrop (1714â1779), a Harvard professor and Fellow of the Royal Society, lived on this site from 1746 until his death. One of colonial America's foremost scientists, he taught mathematics and natural philosophy, observed comets and planetary transits, and helped lay the foundations of American scientific inquiry. The marker honors a scholar celebrated in his day as the greatest American mathematician and philosopher of his time.
James Watson
Cambridge, MA
In these Cambridge rooms between 1955 and 1976, James D. Watson helped drive the revolution in molecular biology that followed the discovery of DNA's structure. From here he also planned the revival of the Cold Spring Harbor Laboratory, which he went on to direct. The site marks a nerve center of postwar American science.
Abbott Lawrence Rotch Memorial
Canton, MA
This memorial in Canton, Massachusetts honors Abbott Lawrence Rotch, who in 1885 founded the Blue Hill Meteorological Observatory on the nearby summit and directed it for the rest of his life. Rotch turned Blue Hill into a world pioneer of upper-air research, using kites and later balloons to probe the atmosphere and advance the young science of meteorology. His private observatory became one of the most important weather-research stations of its era.
