Picking up on kx250rider's post. Nipkow certainly wasn't the first to have the idea of scanning an image for transmission. Bain devised an experimental fax in the 1840s:

I have no idea if anyone had the scanning idea before him. Nor do I know if Nipkow was aware of Bain's work.
As for interlace, Paul Marshall first brought Ulises Sanabria to my attention. This page claims he used interlace in 1926:

A little OT for this thread but a reminder that November this year sees the 75th anniversary of BBC 405 line television. The British vintage Wireless Society will be marking the anniversary with an event at Ally Pally:
