Giovanni Schiaparelli (1835-1910) was an Italian astronomer who worked at the Brera Observatory in Milan(o) and has two claims to fame. In 1866, he calculated the orbits of the Leonid and Perseid meteoroids and realized they were similar to the orbits of the comets Temple-Tuttle and Swift-Tuttle respectively. Thus, he concluded that cometary decay produced meteoroid streams. In the late 1870's, he went on to map the surface of Mars, discovering what he called "canals".
