Recently I was reading the wonderful book by Stefano Mancuso titled “The Revolutionary Genius of Plants”, in which the author describes the work of the great German botanist Wilhelm Pfeffer (9 March 1845 – 31 January 1920). Between 1898 and 1890, Pfeffer decided to use the help of photography in order to study plant movement and was the first person to photograph plants in regular intervals (over a period of several weeks), thus creating the earliest known example of time-lapse photography.

I immediately went on the internet to see if I can find the original time-lapse, and was delighted to find it on YouTube. Here it is!
