Jindal Group, whose interests include steel, power, cement and infrastructure, is chaired by Savitri Jindal, widow of founder Om Prakash Jindal. Upon O.P. Jindal's death in 2005 in a helicopter crash, the group's companies were divided among his four sons, who now run them independently. The biggest assets of the group are overseen by her Mumbai-based son Sajjan Jindal, who runs JSW Steel, among much else. Jindal's younger, Delhi-based son, Naveen, manages Jindal Steel & Power.
