Biography of Oswald Heer

Oswald Heer was a Swiss geologist, paleobotanist, entomologist, and botanist. He was one of the pioneers of paleobotany and gained recognition for his research on the ancient flora and fauna, particularly the Neogene period of the Tertiary system. Heer was a fervent advocate for the hypothesis of the existence of a landmass, known as Atlantis, between America and Europe in ancient times, which explained the nature of the flora during the Tertiary period in Europe.

Heer not only established the characteristics of organic life during this period and the prevailing climate based on fossil remains but also traced the sequential changes in vegetation and determined the approximate average annual temperatures at the beginning and end of this period for various countries.

Early Life and Education

Oswald Heer began studying natural sciences, including entomology under Ernst Friedrich Germar, zoology under Christian Ludwig Nitzsch, and botany under Kurt Sprengel, at the University of Halle in Germany in 1828. He also pursued theology alongside his scientific studies.

After completing his education in 1831, Heer returned to Switzerland and entered the clergy. He conducted geological, botanical, and entomological research in the Tyrolean Alps.

Academic Career and Contributions

In 1834, Heer became a private lecturer in botany and in 1835, he was appointed as a professor of botany and entomology at the University of Zurich. He also served as the director of the Zurich University Botanical Garden. Heer's notable students include Carl Wilhelm von Nägeli, Johannes Theodor Schmalhausen, and Karl Schröter.

In 1843, Heer founded the "Verein für Landwirthschaft und Gartenbau des Kantons Zürich" (Association for Agriculture and Horticulture of the Canton of Zurich). He also co-edited the "Schweizerische Zeitschrift für Land und Gartenbau" (Swiss Journal for Agriculture and Horticulture) with Carl Wilhelm von Regel. Additionally, Heer served as a member of the Canton of Zurich Council for 18 years, from 1850 to 1868.

Recognition and Later Life

In 1876, Oswald Heer was elected as a foreign corresponding member of the St. Petersburg Academy of Sciences. He continued his research and academic contributions until his death.
