Feast day: May 20

St. Bernardine of Siena

Priest & Missionary · 1380–1444

Patron of Advertisers, public relations, gamblers

Franciscan preacher who revived Italy's faith with electrifying sermons and spread devotion to the Holy Name of Jesus, symbolized 'IHS.'

He's the patron of advertising — his 'IHS' monogram campaigns were so effective that playing-card makers complained he was ruining their business.
