Frederik Kaiser

Frederik Kaiser (Amsterdam, 10 June 1808 – Leiden, 28 July 1872) was a Dutch astronomer.

Among his students were Jean Abraham Chrétien Oudemans, Johannes van der Waals, Hendricus Gerardus van de Sande Bakhuyzen and Hendrik Antoon Lorentz.

Kaiser made a series of drawings of Mars at its opposition in 1862 and made a fairly precise determination of its rotational period by comparing his drawings with those of Christiaan Huygens.

Craters on Mars[2] and on the Moon are named in his honour, as well as asteroid 1694 Kaiser.

In Richard Proctor's now-abandoned Martian nomenclature, Syrtis Major Planum was called the "Kaiser Sea".
