Boldface romans, however, are a nineteenth-century invention. Bold
italic is even more recent, and it is hard to find a successful
version designed before 1950. Bold romans and italics have been
retroactively added to many earlier faces, but they are often simply
parodies of the original designs.
Also p 183 description of the Sabon typeface:
Designed by Jan Tschichold. ... The series consists of a roman,
italic and semibold
and p 181 about Palatino:
Designed in 1948 by Hermann Zapf. ... There is a bold weight,
designed in 1950. A bold italic was added, evidently to comobat
existing forgeries, nearly thirty years later.
But beyond this I guess I was wondering if anyone had information
more specifically focused on mathematical typesetting.
