After completing the Pendle Hill Quaker course, Devadas joined the University of Pennsylvania for two semesters[citation needed] and later at the Temple University for further studies.[6][7] This was followed by two courses at the New School for Social Research, New York, one journalism and the other in public relations.[3][6][7] During his time at the institute, he developed a fascination for photography[7] and, on completion of the courses, joined the Indian Embassy in Washington as the official photographer.[3]
Devadas died at age 93, on 26 December 2014, succumbing to a cardiac arrest[7] at his home at Hebrew Home of Greater Washington in Rockville, Maryland.[1][3][5][6][8] He left behind his wife, Kimiko, two daughters, Kamal Cohen and Mina Devadas and six sons, Thambi, Anand, Asoka, Shyam, Arjun and Prem.[3][5][6][8]
He was awarded the civilian honour of Padma Shri[7][8] by the Government of India in 2002.[1][5][6] The civil investiture ceremony was held in Chicago as he was unable to travel to India due to failing health.[3][7][8]
