Giovanni Dondi Dell'Orologio

Giovanni Dondi dell'Orologio (1330–1388), also known as Giovanni de' Dondi, was a doctor and clock-maker in Padua, Italy. He is remembered today as a pioneer in the art of clock design and construction. The Astrarium, which he designed and built over a period of 16 years, was a highly complex astronomical clock and planetarium, constructed only 60 or so years after the very first mechanical clocks had been built in Europe, and demonstrated an ambitious attempt to describe and model the solar system with mathematical precision and technological sophistication.

Famous quotes containing the word giovanni:

    ...I really hope no white person ever has cause to write about me
    because they never understand Black love is Black wealth and they’ll
    probably talk about my hard childhood and never understand that
    all the while I was quite happy.
    —Nikki Giovanni (b. 1943)
