Pliny the Younger (c.62 - c.113) was the nephew and heir of the historian and naturalist Pliny the Elder, who perished in the eruption of Vesuvius in 79 CE. After the latter's death, presumably because he was adopted in the will, he changed his name from Caius Caecilius to Caius Plinius Caecilius Secundus. The famous Verginius Rufus was his guardian.
Originally from Comum in Northern Italy and quite well to do through land holdings, he enjoyed an illustrious legal and administrative career, becoming consul in 100 CE at the age of 39, and finally going to Bithynia on a special commission from the emperor Trajan, where he is supposed to have died. Among his literary friends were Tacitus and Suetonius, and he was a patron of the poet Martial. livius.org has an illustrated biography. And I found this delightful entry from Lippincott's Magazine Of Popular Literature And Science, 1873.
Pliny's modern claim to fame are his letters, a selection of which, numbering 247, he
published in nine books. Book X, his official correspondence (121 letters) with the emperor while
stationed in Bithynia,
was published posthumously, by whom is not known − speculation is that it may
have been Suetonius.
One of my favorites is Pliny's Letter to Gallus (II.XVII), describing his villa at Laurentum (Laurentinum) outside Ostia. Here is a site attempting a reconstruction of the villa with excellent illustrations! The text is excerpted from the Pliny Project, indicating that the actual location of the villa is disputed by some. More − and more (from Le ville di Plinio).
