Final answer:
The person who wrote an important biography of English poets and a novel is not named explicitly, but it is indicative of an author from the Romantic period or thereafter, like William Wordsworth or Alfred Lord Tennyson, who were influential in English literature.
Step-by-step explanation:
The individual who composed an important biography of English poets and a novel is likely to be an author deeply involved in the literary scene. Given the context provided, albeit without a direct name, the characteristics align with prominent figures like William Wordsworth or similar literary figures of the Romantic period. These individuals not only penned biographies and other literary works but also left a significant impact on poetry and the broader landscape of English literature. The individual, therefore, straddled various genres and was recognized for their contributions through appointments or through their subsequent legacies in English literary tradition.
William Wordsworth, for instance, had a lasting impact on literature, not only through his poems as part of the 'Lyrical Ballads' but also through living a life that was entwined deeply with his art. His biography would include his formative relationships with people like Samuel Taylor Coleridge or his sister Dorothy. Similarly, poets like Alfred Lord Tennyson and T.S. Eliot also exhibited lives that reflected their deep engagement with their craft, Tennyson being appointed as Poet Laureate and Eliot becoming a central figure in the Modernist period.
While the question does not specify a name, the thematic elements referred to are characteristic of English literature's history, suggesting that the individual in question left a notable autobiographical touch in both poetry and prose, influencing the perspectives of readers during their time and beyond.
