Lyttelton was a prominent politician for the whig opposition and the group the Cobham circle. Though he began his published career as a poet, as a writer himself Lyttelton also contributed substantially to the opposition campaign. Lyttelton was close to Frederick Prince of Wales, and Lyttelton was widely perceived as the ‘Maecenas’ who brought deserving poets to his royal notice.

Lowth made a name for himself as a very young man through his composition of verses in both English and Latin. He began by writing pious stanzas at age 14, and his career as a poet developed at Oxford, where he wrote Latin verses. Yet it was Lowth's skill as a critic, not a writer, of verse that would win him genuine and widespread fame. While professor of poetry at Oxford, Lowth delivered the thirty-four Praelectiones de sacra poesi Hebraeorum that were to make his name.

Evidently Loveling lived a very licentious lifestyle at Oxford and London, which is reflected in his poetry collection Latin and English Poems. At one point he fled London, perhaps for avoiding imprisonment for debt. He was quite skilled in Latin versification despite his excessive alcohol consumption. DNB states he wrote a creative translation in Imitation of Persius' First Satire (1741) but I can't find it in ESTC.

Lockman was a prolific and much-acclaimed translator; It was said, perhaps with some exaggeration, that Lockman translated ‘with general accuracy, more books for half a century together than any man of his time’ (GM, 314). He translated works of the marquise de Lambert, La Fontaine, Desfontaines, Le Sage, Marivaux, and King Stanislaus, as well as three substantial volumes of French travel writing. His Q and A style histories were extremely popular. He also helped compile a dictionary.

Locker was a barrister who was also known as a man of literature. Some of his poems were published in a miscellany by Mr. Bland. He translated into English part of Voltaire's history of Charles XII and was renowned for his skill in modern Greek. His most important achievement was the work he undertook with Robert Stephens, historiographer royal, on the manuscript letters of Sir Francis Bacon.

Littleton was a clergyman who wrote a humorous poem as an undergraduate, and a pastoral elegy on the death of Ralph Banks, a scholar of King's College, among other poems. Some of his works were printed in GM or miscellanies (such as Dodsley's) and many were published posthumously after he died of a fever. His sermons were also published posthumously for the benefit of his widow and children.

Although Lillo was neither a professional man of the theatre nor at home in literary circles, he was not the naïve artist he is sometimes described as having been. He wrote mostly in verse, but sometimes in prose. Lillo was a playwright who had some wild successes (most notably The London Merchant, which successfully popularized domestic drama), as well as some flops. He enjoyed some royal patronage for some of his works, performing The London Merchant before Queen Caroline and inscribing some of his plays to members of the royal family.

Lewis's birth and death dates are unkown, but he (fl. 1750–1774). Although he's belated according to our standards, he's a particularly interesting case. Writing under the pseudonym "Lancelot Poverty-Struck," Lewis's poems frequently reflect the vicissitudes of a working man's life.

Lewis seemed to have gained considerable success as a poet/playwright, though he was also an usher for a time. His first collection of contemporary poetry was well-received and led him to publish a second. These collections included a wide range of poets writing on various topics; Lewis included his own verses too but did not identify them. He was widely respected for his poetry and highly praised by his friend, Alexander Pope.

Lee was a very successful physician, even attending Frederick, Prince of Wales at one point in his career. He wrote occassional verses while at University and published an oration as Harveian orator in 1736. He died wealthy enough to bequeath funds in his will to build an anatomy school at Christ Church, which was completed at a cost of £1200. In addition, Lee left £140 p.a. for a university readership in anatomy (to which appointments are still made).
