author
Not a single writer but a House of Commons committee, this author credit points to the group appointed in 1849 to investigate Britain's contract packet mail service. The result is a distinctly parliamentary work: formal, factual, and closely tied to the politics of steamship contracts and imperial communications.

by Peninsular and Oriental Steam Navigation Company, Great Britain. Parliament. House of Commons. Select Committee to Inquire into the Contract Packet Service
This author name refers to a committee of the British House of Commons, not to one individual. In Project Gutenberg's record for An Abstract of the Proceedings of the Select Committee of the House of Commons, Appointed Session, 1849, to Inquire Into the Contract Packet Service, the committee is listed as one of the credited authors alongside the Peninsular and Oriental Steam Navigation Company.
The committee was appointed in 1849 to examine the Contract Packet Service—the government-backed mail steamship system that connected Britain with destinations across its empire and beyond. The surviving text is a parliamentary-era document focused on evidence, contracts, and public administration, especially as they related to the Peninsular and Oriental Steam Navigation Company.
Because this is a collective institutional author rather than a person, there is no single life story or personal portrait to tell. What gives the work its interest is its viewpoint: it captures how Victorian Britain investigated transport policy, commercial privilege, and the machinery of long-distance communication in the age of steam.
