Depending on the region you live in, it goes back until 1736 (e.g. Schoenbrunn, Vienna and Mannheim, Germany). In this year, several observatories in Central Europe agreed to take regularly measurements of weather data and keep a log of them.
And yes, that's the time when Daniel Gabriel Fahrenheit (1686 - 1736), Anders Celsius (1701 - 1744) and René-Antoine Ferchault de Réaumur (1686 - 1757) lived, each constructing his own type of thermometer, and defining his own temperature scale.
