He invented an antidote for blood dysentery from an extract of an indigenous medicinal plant and started promoting "modern science".

His father Nrisimha Prasad Datta was a devotee of Hindu god Krishna and his mother Tulasimani was known for her generosity and kindness.

[1] Ram continued his education, in spite of several adversities, at the General Assembly's Institution (now Scottish Church College).

In his official life, he exercised utmost discipline in his dealings with the public and suppliers that he refused to accept any kind of favour to overlook any lapses in standards of supplies and delivery.
