Lala Amarnath: Legendary Indian batsman Lala Amarnath became the first Indian to score a century in Test matches and did that on his debut, hitting a belligerent 118 against England at Mumbai in 1933.
Deepak Shodhan: Deepak Shodhan made a memorable debut against Pakistan, scoring a century after walking in at No 8 at Calcutta in 1952. He thus became the first Indian to score a century in the first innings of his debut Test.
AG Kripal Singh: Kripal scored an unbeaten 100 at Hyderabad, playing against New Zealand in 1955. He was destined for bigger things but an unstable international career meant that he could never attain the heights that looked certain after his debut innings.
