What English font is used for Google's logo?

The Google Logo uses the Catull font, which has been processed with 3D effects using some graphic software (possibly Adobe Photoshop®). Catull was designed by Gustav Jaeger, is copyrighted by Berthold, and is co-marketed by Berthold with companies such as Adobe, Precision Type, and a few others.
