Who was Memmius, the person to whom Lucretius dedicated De rerum natura?

The person to whom Lucretius dedicated his poem De rerum natura was Memmius, who is generally identified as Gaius Memmius.1

He was a notable figure in Roman society, serving as a praetor in 58 BCE and acting as a patron to the poets Catullus and Gaius Helvius Cinna. Additionally, he was the son-in-law of the Roman general and statesman Sulla. Lucretius specifically mentions Memmius in his work, noting that he hoped for his friendship.1

It is important to distinguish this individual from other historical figures of the same name, such as the Gaius Memmius who was a candidate for the consulship and was murdered during the political turmoil involving Lucius Appuleius Saturninus in 100 BCE.23
