Robert Marsham
Edit Profile
Career
From a very early age he had shown a passion for the natural world. In later life, he owned a modest sized country estate in Stratton Strawless, Norfolk and became friendly with the naturalist Gilbert White, with whom he carried on a lengthy correspondence and who described him as a "painful and accurate naturalist" (by "painful" he would have meant "painstaking"). He is best known for his Indications of Spring, the phenology notes in which he recorded 27 signs of spring, starting in 1736 and continuing for over 60 years.
Successive generations of his family added to his work until well into the 20th century and this information now provides immensely valuable data to the United Kingdom phenology database, giving us a wealth of knowledge about how spring is influenced by prevailing weather conditions, This is now of huge interest in the climate change debate.
Marsham was the first to record the effects of nature and seasonal change. Marsham provided insight into the winter of 1739/40, the coldest year on record, when the contents of his chamber pot frequently froze overnight and the turnip crop was completely destroyed.
Turnips, being a Norfolk speciality, feature elsewhere: he regularly recorded turnip flowering dates (needed when turnips were to produce seed). Marsham is still the only person in Norfolk to have recorded the wallcreeper bird.
His interest in trees resulted in his being elected a Fellow of the Royal Society in 1780.
His Indications of Spring were published in "Philosophical Transactions" by the Royal Society in 1789. One of Marsham"s legacies is the Cedrus atlantica, known as the Great Cedar, which he planted in 1747 as an 18 inch sapling.
