Renowned mathematician Vashishtha Narayan Singh died at Patna Medical College and Hospital (PMCH) here on Thursday after prolonged illness.
The premier government hospital in an utter show of callousness denied an ambulance to his family to carry the body.
The mathematician was 74.
Singh, who was released from the PMCH after month-long treatment recently, was rushed back to the hospital again when his condition deteriorated in the morning.
The renowned mathematician, who once worked at NASA and California University, did not get the respect from doctors and officials of the PMCH where he breathed his last.
Expressing grief over Singh's death, Bihar Chief Minister Nitish Kumar said it has caused an irreparable loss to the state and the country.
The chief minister announced that Singh will be cremated with full state honour, an official release said.
Kumar later visited the maths wizard's younger brother Ayodhya Prasad Singh's house near Kulharia complex in Patna and paid floral tributes to him. Prominent leaders from all political parties expressed grief over death of "Vashishtha babu" as he was fondly called by the people.
