Otto Jaekel was born in Neusalz an der Oder in the Freystadt i. Lower Silesian. as the son of a royal Building inspector born. He attended the grammar school in Glogau and the knight academy (Liegnitz) . After graduating from high school, he enrolled at the Silesian Friedrich Wilhelms University .

In 1890 he completed his habilitation at the Friedrich Wilhelms University in Berlin . In 1891 he became curator of the Geological-Paleontological Museum of the Friedrich-Wilhelms-Universität, part of the Museum für Naturkunde (Berlin) . The Geological-Paleontological Museum had been headed by Wilhelm von Branca since 1898 , with whom Jaekel could not get along. Jaekel's 1903 upcoming move to the University of Vienna failed. As the successor to Wilhelm Deecke , he became a professor at the Royal University of Greifswald in 1906 . With his appointment, the previous Mineralogical Institute in Greifswald was re-profiled to the Geological-Mineralogical Institute. In 1908 Jaekel opened the Pomeranian Geological State Collection, which later became the Geological State Collection of Mecklenburg-Western Pomerania . Jaekel dealt with the geological exploration of the Pomeranian coast, with excavations of tank fish near Bad Wildungen and with excavations of dinosaurs near Halberstadt . After his retirement in Greifswald, Jaekel accepted a teaching position at the Sun Yat-sen University (Guangdong) in 1928 . But as early as March 1929, while attending a geological conference in Beijing, he fell ill with pneumonia, which he succumbed to at the age of 66 in the German Hospital .
