Charles P. Butler was the Director of the Madras and Kodaikanal Observatories in 1903, where he advanced solar observation efforts in India. Under his leadership, the Kodaikanal Observatory, established in 1899, focused on sunspots, solar prominences, and solar spectroscopy. His work contributed to solar research, meteorology, and other astronomical observations, helping lay the foundation for future studies in Indian astronomy.

1860 - 1943
Sidney Gerald Burrard (12 August 1860 – 16 March 1943) was a British army officer and geodesist who made significant contributions to surveying in India. He served in the Royal Engineers and later became the Surveyor General of India (1911–1919). Burrard was deeply involved in refining the measurement of the Great Trigonometrical Survey, including work on gravitational anomalies in the Himalayas, which influenced theories about the Earth's shape and crustal structure. He was elected a Fellow of the Royal Society in recognition of his scientific contributions to geodesy and cartography in the Indian subcontinent.

Robert Hanbury Brown (31 August 1916 – 16 January 2002) was a British physicist and radio astronomer best known for his pioneering work in interferometry. Initially contributing to radar development during World War II, he later became a key figure in post-war radio astronomy. Hanbury Brown developed the intensity interferometer, a novel technique for measuring stellar diameters, which he implemented at the University of Sydney’s Narrabri Observatory in Australia. His work significantly advanced observational astrophysics, and he was also noted for his engaging science writing and public outreach.
