Prague and the Coloured Light of the Double Stars
On 30th April 1835 Christian Doppler took his oath as a teacher of elementary mathematics and commercial accounting at the State Secondary School in Prague. The starting annual salary of 800 Guilders, which in the following January rose to 1,000 Guilders, obviously made it possible for him to marry in that year Mathilde Sturm, the daughter of a Salzburg gold and silversmith, and the first of their five children, also Mathilde, was born on 22nd January 1837 (see next chapter, “The Doppler Family”).
