author
1852–1926
A Victorian barrister and legal writer, he is best remembered for clear, practical books on trade-mark law and for a lively history of one of London's old livery companies. His work opens a window onto the legal and civic world of late 19th- and early 20th-century Britain.

by Lewis Boyd Sebastian
Called to the bar and active as a legal author, he wrote extensively on trade-mark law at a time when modern commercial branding was taking shape. His books include The Law of Trade Marks and Their Registration, The Law of Trade Mark Registration, and A Digest of Cases of Trade Mark, Trade Name, Trade Secret, Goodwill, etc.
He also wrote An Old City Company: A Sketch of the History and Conditions of the Skinners' Company of London, a work that blends institutional history with personal knowledge. In its preface, he notes that he had been apprenticed to the Skinners' Company and later served it through several wardenships and two masterships, suggesting a long and close connection with the civic life of the City of London.
Published records identify him as Lewis Boyd Sebastian (1852–1926). Reliable biographical detail beyond his legal career, authorship, and links to the Skinners' Company is limited in the sources I could confirm here, so this portrait stays close to the documented record.
