Kālidāsa
The most popular theory is that Kalidasa flourished during the reign of Chandragupta II, and therefore lived around 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kalidasa in this period. According to this theory, his career might have extended to the reign of Kumaragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
Job Charnock
A landmark Calcutta High Court ruling on 16 May 2003, based on a report from an academic committee consisting of Dr. Nemai Sadhan Basu, Prof. Barun De, Prof. Sushil Chaudhri, Prof. Arun Dasgupta and Prof. Pradip Sinha found that a 'highly civilised society' and 'an important trading centre' had existed on the site of Calcutta long before the first European settlers came down the Hooghly. They also found the place then called Kalikatah was an important religious centre due to the existence of the Kali temple in the adjacent village of Kalighat. The first literary reference to the site is found in Bipradas Pipilai's magnum opus "Manasa Mangala" which dates back to 1495. Abul Fazl's "Ain-I-Akbari" dating 1596 also mentions the place. The Sabarna Roy Choudhury family was granted the "Jagirdari" of Kalikatah by Emperor Jehangir in 1608. The report added that Charnock's name was just the first of those, including Eyre, Goldsborough, Lakshmikanta Majumdar (Laksmikanta Roy Choudhury), the Sett Bysack families and Sabarna Choudhuries, that could be celebrated for developing the city. The court declared that "Charnock ought not to be regarded as the founder of Calcutta", and ordered government authorities to purge his name from all textbooks and official documents containing the history of the founding story of the city.
