The Working Group for the History of Astronomy will hold a Colloquium on
,,Development of Astrophysics'', on Monday, September 26, 2005 in Köln.
The emphasis of the topic ,,Development of Astrophysics'' is the rise of theoretical astrophysics in the 20th century. In the Einstein-Year 2005 (100th birthday of the Special Theory of Relativity and 50th year of Einstein's death) it is clear that Albert Einstein (1879-1955) plays an important role. The General Theory of Relativity (ART), published in 1915, had important consequences for the development of cosmology, for our conception of space, time and matter. Erwin Finlay-Freundlich (1885-1964) tried to verify the ART empirically. In this context one should also mention Karl Schwarzschild (1873-1916), who was the first to derive exact solutions of the Einstein field equations. In his research in 1915 he introduced the Schwarzschild radius.
Already the radiation theory is the prehistory for theoretical astrophysics. Since the turn of the century astrophysics came into existence parallel to the rise of theoretical physics. Here topics like structure and development of the Sun and the stars - Robert Emden (1862-1940), Arthur Stanley Eddington (1882-1944) - as well as the question of energy production should be mentioned. But also the theme development of computing technology and the introduction of the computer should be included, a precondition for large model calculations.
Finally in 1920, the Saha theory - Megh Nad Saha (1894-1956) - offered the basis
for the interpretation of stellar spectra and the physical conditions in the
stellar atmospheres. The eminant figure in astrophysics in Germany in the 1930s
and 1940s was Albrecht Unsöld (1905-1995), who has his 100th birthday in
this year. His main result and success was the quantitative composition of
stellar atmospheres and the abundance of elements in the cosmos.
