Attribution - Are the Wrong People Getting Credit?

I'm embarrassed to say, it happened to me again this week, and I froze.  A project I was the primary developer on about 5 years ago was being praised by my counterpart in another part of my organization for its innovativeness and usefulness.  The only problem is that this counterpart was praising someone else for the work - a male engineer.  I didn't correct the error.  Now, the person being praised indeed deserves a share of the credit - he contributed to the project in very important ways - but it was neither his idea nor primarily his product.  Later, I was promoted, and I'm now that male engineer's supervisor, so on one level I was quite happy to allow the praise to be assigned to my employee, but on another level, I regret that I allowed a male to gain credit for work done by a female.
