Agustus Horatio Montrose (1830–1899) was an English novelist and playwright operating in the northeast of London in the mid to late 19th century. He is especially notable for one novel (see Lilies In December) and several plays, although he wrote 22 known pieces and there is a possibility that more were created unknown to the scholars who study him. He is considered influential to many later 19th and 20th century authors, including Joseph Conrad. Spending a life in semi-poverty with only moderate success, Montrose was popular among many citizens. Two of his plays have been banned by various Private Libraries. When asked about the abnormal parody of the name Augustus, Montrose said, "My mother liked the name Augustus, but was absolutely an individual and she didn't want a name for me that would be common. Thus she decided upon Agustus, to be pronounced identically to Augustus but spelled without the 'u'."
