Are you looking for the Renaissance Venetian Printer Aldus Manutius?*
This is the wiki-entry for Hermann Zapf's typeface Aldus
A digital version of Aldus is available from Linotype, Adobe, and their partners.
See the Palatino thread for more information.
* Aldus is not a revival of types commissioned by Aldus Manutius. Rather, it is drawn in a general Italian Renaissance style and named in honor of his contribution to the world's typographic development.
