# Doppelmaier, John Gabriel

, a German mathematician, was born at Nuremberg in 1677, and was first
intended by his family for the bar, but soon relinquished
the study of the law for that of mathematics, in which he
was far more qualified to excel. He became professor of
mathematics at Nuremberg, after having travelled into
Holland and England to profit by the instructions of the
most eminent scholars in that science. In England he became acquainted with Flamstead, Wallis, and Gregory,
and in 1733, long after he returned home, was elected a
fellow of the royal society as he was also of the societies
of Petersburgh and Berlin. His works, in German, on
astronomy, geography, and mathematics, are numerous.
He also published some in Latin: “Nova Methodus parandi Sciaterica Solaria/' 1720.” Physica experimentis
illustrata,“4to;” Atlas Ccelestis," 1742, fol. Doppelmaier made some curious experiments in electricity, at the
latter part of his life, which he also published; and translated the astronomical tables of Stretius, French and
English, into Latin. ^{2}
