He was born in Gross-Brese near Perleberg. His earliest work was the editing in 1794 of an astronomical almanac for the Prussian government. He taught mathematics and mechanics in the school of woods and forests, and also in the military school.

He devoted his life chiefly to the examination of ancient systems of chronology. In 1825–1826 he published his great work, Handbuch der mathematischen und technischen Chronologie, re-edited as Lehrbuch der Chronologie ; a supplementary volume, Die Zeitrechnung der Chinesen, appeared in 1839 in Berlin.
He wrote also Historische Untersuchungen über die astronomischen Beobachtungen der Alten, Untersuchungen über den Ursprung und die Bedeutung der Sternnamen and Über den Ursprung des Thierkreises. With Nolte, he published handbooks on English and French language and literature.
His son, Julius Ludwig Ideler, wrote Meteorologia veterum Graecorum et Romanorum — Prolegomena ad novam Meteorologicorum Aristotelis — Editionem adornandam..
