Manlio Martinelli (1884–1974) was an Italian painter active in Livorno.
He was born in Livorno, and trained under Guglielmo Micheli, along with Gino Romiti, Llewelyn Lloyd, Amedeo Modigliani, and Aristide Sommati. He was a member of the Gruppo Labronico of painters that met in the Caffè Bardi.
He differed from the Macchiaioli schools who had portrayed landscapes and scenery in naturalistic light; his themes were intimate and centered on people: often portraits, but could be iconic scenes of mothers and children or just toddlers. His colors were bright, with solid blocks, more expressionist than divisionist.[1] A retrospective was held at the Pinacoteca Carlo Servolini of Collesalvetti in 2010, titled Manlio Martinelli 1884-1974 Un amico di Modigliani alla Scuola di Guglielmo Micheli, curated by Francesca Cagianelli.[2] [3]
