BIOGRAPHY

Ferdinand Cohn was bornon 24 January 1828 in Wrocław, Poland, Polish, is Founder of Bacteriology and Microbiology. Ferdinand Cohn was a German biologist born in the nineteenth century in Breslau, under German Kingdom. He is best known as the father of bacteriology and microbiology. A child prodigy, he entered the University of Breslau to study botany at the age of 16. However, because of his Jewish background he was not allowed to take his final examination. So he shifted to more liberal University of Berlin and gained his doctoral degree at the age of nineteen. Subsequently, he went back to Breslau to take up a teaching job at the Breslau University and remained there till his retirement. However, he became more famous as a researcher. He first started working with algae and established that protoplasm contained the basic characteristics of all life. He then went on to establish the existence of sexual process in those unicellular organisms. Later he concentrated on bacteria and classified them under four groups. His discovery of endospores in Bacillus subtilis is another of his important achievements. During his lifetime, he published more than 150 research reports. Under him, the University of Breslau became an innovative center for plant physiology and microbiology.

TIMELINE
1876

In 1876, Cohn met Robert Koch, then an unknown doctor

1872

In 1872, Cohn was promoted to the post of full professor

1870

In 1870, Cohn founded a new journal called Beiträge zur Biologie der Pflanzen (Contributions to the Biology of Plants), primarily for publishing the works done in the Institute of Plant Physiology

1867

In 1867, Cohn published another paper in which he suggested that these algae must have been the first inhabitants of earth

1866

In 1866, he was able to establish a separate Institute for Plant Physiology at the University of Breslau after a long struggle

1865

In 1865, he published another important paper on his experimental study of phototropism in microscopic organisms

1859

In 1859, he was appointed extraordinary professor of botany

1856

In 1856, he observed the same phenomenon in Volvox globator, another species of green algae

1855

In 1855, Cohn observed the formation of spermatozoa in Sphaeroplea annulina, a genus of green algae and followed the progress all the way to the eggs

1854

In 1854, he also concluded that bacteria are plants, not animals

1850

Therefore in 1850, Cohn began his study on unicellular algae Protococcus pluvialis with special emphasis on protoplasm

1849

This attitude sealed his career in Berlin and he returned to Breslau in 1849

1848

The third important factor was that, in 1848, Heinrich Goppert, under whom Cohn had studied botany at Breslau, had asked him to concentrate on algae

1847

Therefore, he shifted to the more liberal University of Berlin in October 1846 and received his doctoral degree in botany from there on 13 November 1847 at the age of 19

1842

He soon overcame such emotional impediment and entered the University of Breslau in 1842

1835

In 1835, he was enrolled at Maria Magadalena Gymnasium

1828

Ferdinand Cohn was born on 24 January 1828, in the Jewish quarter of Wroclaw, Poland
