He observed the planet [[Mars]] with great detail. In 1909 he was credited with discovering clouds on the planet. During the campaign to observe [[Mercury (planet)|Mercury]] between 1924 and 1929, he was the only experienced observer who doubted the deduced rotational period. It later (in 1965) turned out to be incorrect.

A [[Impact crater|crater]] on Mars was named in his honor.
