From 1906 to 1917 he directed the Agricultural Higher Institute of Portici, in which, thanks to Vincenzo de Cesati, he begun teaching since 1877 as assistant of Nicola Pedicino for the chair of botany, to whom he succeeded in 1880.
Orazio Lomi Gentileschi (1563–1639) was an Italian painter. Born in Tuscany, he began his career in Rome, painting in a Mannerist style, much of his work consisting of painting the figures within the decorative schemes of other artists. After 1600, he came under the influence of the more naturalistic style of Caravaggio. He received important commissions in Fabriano and Genoa before moving to Paris to the court of Marie de Medici. He spent the last part of his life at the court of Charles I of England. He was the father of the painter Artemisia Gentileschi.
