Sir William Schwenck Gilbert was born at 17 Southampton Street just off the Strand in London on November 18th 1836. He was a man of a great many talents; dramatist, librettist, poet and illustrator. Of course he is better known as the collaborator with Arthur Sullivan of 14 light comic operas under that world famous moniker Gilbert & Sullivan. They continue to be performed and to entertain millions every year from commercial theatres down to amateur dramatic societies and schools. Here we publish his libretto for Trial By Jury & Thespis.
