I was reading thru the bio of Periasami Thooran at http://entertainment.vsnl.com/thooran/T ... raphy.html
A few points stand out. He:
1. had a graduate degree in pure maths and astronomy!
2. has written several books on psychology, even one on embryology!
3. worked on Tamil and children's encyclopedia
Some of his famous compositions:
tAye tripurasundari - SuddhasAveri
murugA murugA - savEri
kaliyuga varadan - brindAvana sAranga
He passed away as recently as 1987, but there doesn't seem to be a single picture of his available anywhere!
