All the Britishers on the Board were members of the Indian Civil Service (ICS), which was an exclusive institute.
Frank D'Souza was neither an ICS officer nor a university graduate at the time, but was considered brilliant.
His findings were reported in a paper titled "Review of the Working of the Rules and Orders Relating to the Representation of Minority Communities in the Services of the State-managed Railways" that was published in 1940.
Upon completing his job in Pakistan, Frank returned to India and donated his house in Karachi to an order of nuns, the Sisters of Mercy, to be used as a home for the aged.
Later, one of his sons, Reverend Father Ronald Alexander D'Souza, a Catholic priest who worked in Lahore, lived the last few years of his life at the home.
