an English courtier, politician, author and diplomat, and the brother of King Henry VIII's fifth queen, Catherine Howard. Howard held offices at court under four monarchs, Henry VIII, Edward VI, Mary I, and Elizabeth I, most notably the office of Master of the Armoury, and undertook several diplomatic missions. A masque written by Howard was produced at court during the reign of Edward VI, and he is mentioned by name in the Langham letter, which describes the Earl of Leicester's entertainment of Queen Elizabeth at Kenilworth Castle in July 1575.
