Leone Battista Alberti invented the first anemometer (an-uh-mom-i-ter) in 1450. It was a swing anemometer that was later redesigned in the 1800s. An anemometer measures the wind's velocity and pressure. Leone's anemometer measured velocity. Leone Alberti was not only an inventor but also an architect, author, painter, poet, philosopher, and cryptographer. He is best known for his architectural works and his writings on painting, beauty, and architecture. Leone was also important to the field of cryptology. He invented the first polyalphebetic cipher and machine assisted cipher disk. Some even call him the father of western cryptology. He was the illegitimate son of Lorenzo Alberti. Because of this he was able to go to the best schools in Italy. Before his inventing, he received a doctorate in cannon law and served as papal inspector of monuments.
