⭐Biographical 🪶Note on Relativity Theory

BIOGRAPHICAL NOTE…

ALBERT EINSTEIN is the son of German-
Jewish parents. He was born in 1879 in
the town of Ulm, Würtemberg, Germany.
His schooldays were spent in Munich, where he
attended the Gymnasium until his sixteenth year.
After leaving school at Munich, he accompanied his
parents to Milan, whence he proceeded to Switzer-
land six months later to continue his studies.
From 1896 to 1900 Albert Einstein studied
mathematics and physics at the Technical High
School in Zurich, as he intended becoming a
secondary school (Gymnasium) teacher. For
some time afterwards he was a private tutor,
and having meanwhile become naturalised, he
obtained a post as engineer in the Swiss Patent
Office in 1902, which position he occupied till 1909.

The main ideas involved in the most important
of Einstein’s theories date back to this period.
Amongst these may be mentioned: The Special
Theory of Relativity, Inertia of Energy, Theory of
the Brownian Movement, and the Quantum-Law
of the Emission and Absorption of Light (1905).
These were followed some years later by the
Theory of the Specific Heat of Solid Bodies, and the
fundamental idea of the General Theory of Relativity.
During the interval 1909 to 1911 he occupied
the post of Professor Extraordinarius at the
University of Zurich, afterwards being appointed
to the University of Prague, Bohemia, where he
remained as Professor Ordinarius until 1912.
In the latter year Professor Einstein accepted a
similar chair at the Polytechnikum, Zurich, and
continued his activities there until 1914, when
he received a call to the Prussian Academy of
Science, Berlin, as successor to Van’t Hoff.
Professor Einstein is able to devote himself
freely to his studies at the Berlin Academy, and
it was here that he succeeded in completing his
work on the General Theory of Relativity (1915–
17). Professor Einstein also lectures on various
special branches of physics at the University of
Berlin, and, in addition, he is Director of the
Institute
*
for Physical Research of the Kaiser
Wilhelm Gesellschaft.
Professor Einstein has been twice married.
His first wife, whom he married at Berne in 1903,
was a fellow-student from Serbia. There were
two sons of this marriage, both of whom are liv-
ing in Zurich, the elder being sixteen years of age.
Recently Professor Einstein married a widowed
cousin, with whom he is now living in Berlin.
