Carl Louis Schwendler

Carl Louis Schwendler (1838–1882) was a German electrician and one of the first proponents of the tungsten based incandescent light bulb.

He was involved in setting up telegraphic communication between Agra and Calcutta[1] solving problems in transmission of submerged cables.

In 1867 a zoo was proposed by Joseph Fayrer and the idea was again raised by Schwendler in 1873.

[4] The Zoological Gardens were formally inaugurated on 1 January 1876 by the Prince of Wales (King Edward VII) and opened to the public in May with Schwendler as its first superintendent assisted by Ram Brahma Sanyal.

This zoo became in 1875 the home of Robert Clive's tortoise, Adwaita, thought to be the longest-living animal in the world when he died in 2006 at an estimated of age 255.
