Wikipedia is your friend isn't it?
Looks like it is; in either case, it seems that those five drivers are the ones that Wizzie is looking for.
On another note, for those wondering about the question I set about the use of titanium, I guess that I might as well answer it. The teams that I was thinking of (or, at least I am aware of as being the first to use titanium) were Ensign and Team Lotus. Ensign used a titanium alloy for the pedals in the 1980 N180 car, for weight reduction; the famous accident in question was the 1980 Long Beach GP, where the brake pedal snapped and Regazzoni crashed heavily, resulting in severe spinal injuries.
The other attempt was by Team Lotus, where they used titanium to manufacture suspension arms in the early 1980's, in an attempt at weight reduction (steel being the more conventional material at the time). However, the technicians made the mistake of trying to make the suspension parts by welding the parts together without the use of an inert atmosphere. Due to the high temperatures used, the titanium would react with the oxygen and nitrogen in the atmosphere, resulting in a brittle weld which cracked when tested.
They also tried copying Ensign's tactics of titanium pedals (and again premature failure of the pedal caused De Angelis to crash, although thankfully he was unharmed), and even titanium springs, which they quickly abandoned due to creep under load.
