Vaswani — the moral force behind the Sadhu Vaswani Mission and a tireless promoter of vegetarianism and animal rights — passed away on Thursday, aged 99, days short of his centenary.Sources at the Sadhu Vaswani Mission said he had been admitted to a private hospital in the city for the past a few days and was discharged on Wednesday night. Dada Vaswani died on the mission premises on Thursday.Born Jashan Pahlajrai Vaswani on August 2, 1918 in the city of Hyderabad in Sindh province (present-day Pakistan), he was a brilliant student in his youth, who matriculated at the tender age of 13 and graduated at 17.His M.Sc. Thesis on the ‘Scattering of X-Rays by solids’ was examined by Nobel Laureate C.V Raman.Acclaimed as a humanitarian and non-sectarian leader, he later gave up a promising academic career to follow in the footsteps of his uncle, Sadhu T.L Vaswani – the legendary Indian educationist who started the Mira Movement in education.In order to propagate Sadhu Vaswani’s ideas and vision, he edited three monthly journals – the Excelsior (which became a popular journal), the India Digest and the East and West series.He also served as one of the earliest Principals of the St. Mira’s College for Girls.
