  • 1054: Composer, mathematician, and astronomer Hermann of Reichenau dies. He wrote a treatise on the science of music, several works on geometry and arithmetic, and astronomical treatises (including instructions for the construction of an astrolabe, at the time a very novel device in Western Europe).
