Max Schönwetter
Max Schönwetter (23 August 1874 – 21 April 1961) was a German ornithologist. He studied the eggshells of birds in detail and published around 40 papers. He produced a four volume work on the eggs of birds, the handbook of oology which was published from 1961 and completed after his death by Wilhelm Meise, the last part coming out in 1992. His collections of nearly 18000 eggs of nearly 4000 species are now held at the University of Halle-Wittenberg.
