Life
Ernst Haeckel was born on February 16, 1834, in Potsdam (then part of Prussia). In 1852, Haeckel completed studies at Cathedral High School (Domgymnasium) of Merseburg. He then studied medicine in Berlin and Würzburg, particularly with Albert von Kölliker, Franz Leydig, Rudolf Virchow (with whom he later worked briefly as assistant), and with anatomist-physiologist Johannes Peter Müller (1801–1858). Together with Hermann Steudner he attended botany lectures in Würzburg. In 1857, Haeckel attained a doctorate in medicine (M.D.), and afterwards he received a license to practice medicine. The occupation of physician appeared less worthwhile to Haeckel, after contact with suffering patients.
Haeckel studied under Karl Gegenbaur at the University of Jena for three years, earning a doctorate in zoology, before becoming a professor of comparative anatomy at the University of Jena, where he remained for 47 years, from 1862 to 1909. Between 1859 and 1866, Haeckel worked on many invertebrate groups, including radiolarians, poriferans (sponges) and annelids (segmented worms). During a trip to the Mediterranean, Haeckel named nearly 150 new species of radiolarians. Haeckel named thousands of new species from 1859 to 1887.
From 1866 to 1867, Haeckel made an extended journey to the Canary Islands with Hermann Fol and during this period, met with Charles Darwin, in 1866 at Down House in Kent, Thomas Huxley and Charles Lyell. In 1867, he married Agnes Huschke. Their son Walter was born in 1868, their daughters Elizabeth in 1871 and Emma in 1873. In 1869, he traveled as a researcher to Norway, in 1871 to Dalmatia, and in 1873 to Egypt, Turkey, and to Greece. Haeckel retired from teaching in 1909, and in 1910 he withdrew from the Evangelical church. Haeckel's wife, Agnes, died in 1915, and Haeckel became substantially more frail, with a broken leg (thigh) and broken arm. He sold the mansion Medusa ("Villa Medusa") in Jena, Germany in 1918 to the Carl Zeiss foundation, and it presently contains a historic library. Haeckel died on August 9, 1919.

Famous quotes containing the word life:
“Today brings the sad, glad tidings that Mrs. Abraham Lincoln has passed from that darkness which had fallen upon her path through this life, out into the light and joy of that life toward which her vision has so long been strained.
Modern education is lethal to children.... We stuff them with mathematics, we pummel them with science, and we use them up before their time.”
—Honoré De Balzac (1799–1850)
“In a period of a people’s life that bears the designation “transitional,” the task of a thinking individual, of a sincere citizen of his country, is to go forward, despite the dirt and difficulty of the path, to go forward without losing from view even for a moment those fundamental ideals on which the entire existence of the society to which he belongs is built.”
—Ivan Sergeevich Turgenev (1818–1883)
