Hermann Alexander Brück CBE FRSE (15 August 1905 – 4 March 2000) was a German-born astronomer, who spent the great portion of his career in various positions in Britain and Ireland.

[1] Young Hermann was educated at the Kaiserin Augusta Gymnasium in Berlin-Charlottenburg, a school specialising in the Classics (Latin and Greek), where he also had excellent teachers in mathematics and physics.

While there, Brück participated in the physics colloquium at the Humboldt University of Berlin with the physicists Max von Laue and Albert Einstein and the astronomer Walter Grotrian.

[citation needed] With growing difficulties under National Socialism, Brück left Germany in 1936 to take a temporary research assistantship at the Vatican Observatory.

In time, Brück became Assistant Director of the Observatories and John Couch Adams Astronomer, specialising in solar spectroscopy.

This technology enabled spectra to be reduced in minutes rather than months, which gave astronomers time to focus on other activities.

At this time, his second wife and colleague, Dr. Mary T. Conway,[7] initiated a historical study of nineteenth-century astronomy, which resulted in the publication of a book on Charles Piazzi Smyth, one of Brück's predecessors.
