Mr Thiagharan’s time with WUS spanned the years 1957 to 1976. He was elected student general secretary of Madras University WUS, then student executive secretary of WUS India and finally executive secretary of WUS India for 14 years. He oversaw the shift in WUS activity from services for students, to student involvement in development in local communities and regional assistance projects. At very short notice he organised the 1970 International WUS General Assembly and was involved with other international WUS activities. After WUS he undertook private business ventures. Sadly, he died in April 2021.
