⁂ Nicolas Fatio de Duillier was a Swiss mathematician known for his work on the Zodiacal light problem and for his close working relationship with Sir Isaac Newton. In 1699 he suggested increasing fruit-tree and vine productivity by using sloping walls and later a tracking mechanism which could pivot to follow the sun.
