Ferdinand Cohn was bornon January 18, 1924 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.

Biography/Timeline

1847

Ferdinand J. Cohn was born in the Jewish quarter of Breslau in the Prussian Province of Silesia (which is now Wroclaw, Poland). His Father, Issak Cohn, was a successful merchant and manufacturer. At the age of 10 Ferdinand suffered hearing impairment (for an unknown reason). Starting at age 16 he studied botany under Heinrich Goppert at the University of Breslau. Due to Cohn's Jewish background he was prevented from taking the final degree examinations at Breslau. He then moved to the University of Berlin. At age 19 in 1847 he received a degree in botany at Berlin. He remained studying botany for another couple of years in Berlin, where he came in contact with many of the top Scientists of his time.

1849

In 1849 he returned to the University of Breslau and he remained at that university for the rest of his career as a Teacher and researcher. On his initial return to Breslau in his early twenties, his Father had bought for him a large and expensive microscope made by Simon Plössl. This microscope, which the University of Breslau and most universities did not have, was Ferdinand Cohn's main research tool in the 1850s. In the 1850s he studied the growth and division of plant cells. In 1855 he produced papers on the sexuality of Sphaeroplea annulina and later Volvox globator. In the 1860s he studied plant physiology in several different aspects. From 1870 onward he mostly studied bacteria. He established the use of sterile culture mediums and rediscovered the botanical garden of Lorenz Scholz von Rosenau in Breslau. He published over 150 research reports during his lifetime. The University of Breslau became an innovative center for plant physiology and microbiology while he was there.
