The Family Legacy Edit
Ketkar family inherited an ancestral legacy that would make one feel proud. The family of Venkatesh Bapuji Ketkar originated from a small village called "Ketaki Bivali", near Chiplun, situated in the Konkan belt of Maharashtra. Its history dates back to the period of Chhatrapati Shivaji Maharaj. After the assassination of Sambhaji Maharaj, Mughals established their stronghold in maharashtra. Many Maratha chiefs and soldiers took military action against the Mughal stronghold. Among these was a chieftain named Bhālerāo, who led raids called Bhalerāī. The Bhalerāī raids caused chaos, resulting in the migration of many families, including the Ketkar family. Ketkar's ancestors settled in Paithan (Pratishthan) on the banks of Godavari river. Paithan was famous in eighteenth-century Maharashtra for education, moneylending and textile. Paithan was also the ancient capital of king Śālivāhana, initiator of the famous shalivahan Śaka. The ancestral business of the Ketkar family was of the apparels of zari work. (a weave of golden or silver threads) The business suffered many ups and downs over the time. During the time of Sakharam Ketkar (grandfather of Vekatesh Ketkar), the business suffered big losses, and had to be closed down eventually. On January 15, 1815, Ramkrishna alias Bapuji Ketkar was born to Sakharam Ketkar on the next day of Makar Sankraman. Bapu Shastri Ketkar was born with innate intelligence. At an early age, he mastered grammar, Vedānta and astronomy. He had tremendous expertise over astronomy. Bapu Shastri realised that after Ganesha Daivajna (born 1507 AD), there was no remarkable progress in Indian astronomy. During this period many important changes took place in astronomical sciences in the west. Newton proposed the law of gravity. Galileo invented the telescope. But in India, the progress was not as profound and remarkable as it should be. The astronomical calculations of events like eclipses,evolved from the book 'Suryasiddha Grahalaghav' did not match with the calculations of Western texts. After observing this, Bapu Shastri Ketkar wrote a book called 'Jyotishashastra Subodhini', in Sanskrit. Bapushastri was also a music lover. After acquiring proficiency in academics at the age of 27, he decided to study Rudraveena, an instrument of Indian classical music. In order to master the instrument, he prepared to move to Thanjavur, the stronghold of Rudraveena. But on the way, he met Pandit Vaikobuwa Mhaisksr, a master of Rudraveena. During this visit, Panditji urged him to settle in Nargund near Gadag in Karnataka (which was a marathi province) and learn Rudraveena from him. Bapu Shastri accepted this offer and in a short interval of time his fame spread far and wide among many scholars there. The court of Nargund Sansthan recognized his merits in a very short time. In the changing circumstances that followed the War of Independence of 1857, the Maharaja of Nargund handed over this gem to the Ramdurg Sanatan. He acquired royal patronage and great honor there. At the request of the King of Ramdurg, he translated Professor Kero Laxman Chhatre's Marathi treatise 'Grahasādhana' into Sanskrit.

In the Siddhanta dynasty of Aryabhata, Bhaskara, and Madhava, he is the very last great astronomer. Before Clyde Tombaugh found Pluto in 1930, he considered the possibility of the ninth planet with impressive calculations in 1911.
