Wirth didn't produce anything usable before Oberon (which is garbage collected, so outside of the C niche.)

And yet despite of it doing everything that fits the niche http://www.projectoberon.com :-)

Modula-2 was quite usable and Mac OS/Lisa Object Pascal was designed with collaboration from Wirth.

As for Oberon, Astrobe is still in business.
