Thomas Edison (1847 – 1931, an American inventor who developed many devices including the electric light bulb) tried two thousand different materials in search of a filament for the light bulb.
When none worked satisfactorily, his assistant complained, “All our work is in vain. We have learned nothing.”
Edison replied very confidently, “Oh, we have come a long way and we have learned a lot. We know that there are two thousand elements which we cannot use to make a good light bulb.” - Stephen (academictips.org)
