Major General William Cullen (17 May 1785 – 1 October 1862[1]) was a British Army Officer with the Madras Artillery Regiment, and from 1840 to 1860, Resident in the Kingdom of Travancore and Cochin.
Cullen was posted in India in 1804 and his early service was at Khandeish and Berar as part of the Hyderabad subsidiary force.
He was part of the reinforcement sent from Madras to fight the French and was present during the capture of St. Denis in Bourbon in July 1810 during the Napoleonic Wars.
The museum project was aided by John Allan Broun, an astronomer and geologist who also maintained careful meteorological records around Trivandrum.
His notes on the topic which were compiled by Edward Balfour questioned the premise and pointed out the lack of precise data ("facts") in the claims ("opinions") made by Alexander von Humboldt on deforestation leading to desiccation.
William Henry Sykes requested him to send samples of Roman gold coins discovered in 1851 at a village on a hill about ten miles east of Cannanore.
