The 3rd Earl of Rosse, also known as William Parsons, was a prominent figure in the progress of science during the Victorian era. Born in 1800, he dedicated his life to astronomy and made significant contributions to the field. One of his most notable achievements was the construction of The Great Telescope at Birr Castle in Ireland. Built between 1828 and 1845, this impressive structure had a diameter of 72 inches (1. 8 meters) and was considered one of the largest telescopes in the world at that time. Lord Rosse's telescope allowed him to observe celestial objects with great detail. In fact, he drew a spiral galaxy in Canes Venatici based on his observations in 1850. This drawing by Lord Rosse himself showcases his keen eye for detail and artistic talent. His dedication to scientific advancement extended beyond his own research. Lord Rosse played an important role in popularizing science as well. He collaborated with renowned British astronomer Robert Stawell Ball, who became famous for his lectures and writings on various scientific subjects. The Ouse Bridge photograph from York taken in 1844 gives us a glimpse into the Victorian era when Lord Rosse lived. It captures a moment frozen in time - a testament to both technological advancements like photography itself and societal developments during that period. Birr Castle, located in County Offaly, Ireland served as Lord Rosse's home throughout these endeavors. The castle stands tall even today as a reminder of its historical significance within scientific circles. Lord Rosses' legacy lives on through these photographs and drawings that capture moments from different stages of his career – from constructing The Great Telescope to observing spiral galaxies like M51 or Canes Venatici.
