Begun by Frere-Jones while he was a student, it was originally used in AIGA's magazine and released commercially by Font Bureau.[2][3] It was named for the then-executive director of AIGA, Caroline Warner Hightower.[4][5] It has been included with some Microsoft software such as versions of Microsoft Office.[6] Some releases have been called "High Tower Text".
The family includes an italic style; this is Frere-Jones' design, since this style only emerged after Jenson's death. A commercial release is sold by Font Bureau in the OpenType format, which includes small capitals, ligatures and both lining and text figures.[7] It does not include a bold style, which did not exist in Jenson's time.
