1. Do you know who the inventor of the camera is?
2. Do you know who is the inventor of the camera?
Which is the correct sentence? I think it is the first one.
Thanks.
Of the two, I prefer the first, though both are possible.
I'd probably say: Do you know who the inventor of the camera was?
or: Do you know who invented the camera?
