Actor Kalki Koechlin is the great-granddaughter of Maurice Koechlin, the French-Swiss engineer who designed and built the Eiffel Tower with Gustave Eiffel. Trained at ETH Zurich, Maurice sketched the iconic 300-metre tower in 1884, led 5,300 design drawings, and oversaw construction from 1887 to 1889, a legacy connecting Paris’s landmark to Indian cinema.
