Who is Nicodemus from Life of Christ and what is their importance?

Nicodemus was a Pharisee. He was a man of wealth and status. Christ taught Nicodemus the doctrine of Baptism—that a man must be reborn "of water and the spirit" in order to enter into the kingdom of God. Nicodemus was present after the Crucifixion and, along with Joseph of Arimithea, helped find a spot to bury Christ.
