Sir Sidney Lee,
A Life of William Shakespeare
“ The Earl of Pembroke known only as Lord Herbert in youth.The nobleman under consideration succeeded to the earldom of Pembroke on his father’s death on January 19, 1601 (N. S.) , when he was twenty years and nine months old, and from that date it is unquestioned that he was always known by his lawful title. But it has been overlooked that the designation ‘Mr. William Herbert,’ for which the initials ‘Mr. W. H.’ have been long held to stand, could never in the mind of Thomas Thorpe or any other contemporary have denominated the Earl at any moment of his career. ”
