Arena Stage and Invitrogen Logos - Have you seen this font they share?

You've probably seen this font before. Work for Arena Stage theater in D.C. has been featured in design annuals for several years. The same typeface used in the Arena Restaged logo (I believe) is used in this logo for Invitrogen, a biotech company.

Can anyone help me ID this font?



Oh my. You're GOOD.

You found in a minute and a half what I failed to find in an hour.

Many, many thanks.

Just one of those faces that is burned on my memory. :^) You're welcome.
