Fritsch at the Queen Mary College from where he received a PhD.[1][2]
Iyengar was an active sportsman and swimmer. He rescued two of his students from drowning in the Pamban in 1925. He was also a billiards champion in Madras. He died from cerebral thrombosis.[3][4]
Several taxa have been named after him including Iyengaria [4](Punctariaceae), Iyengarina (Dematiaceae), Iyengariella (Stigonemataceae), and Parthasarathiella (Stigonemataceae).
