In early Drum & Bass, the "Reese" bassline was a massive part of things, and it comes from Kevin "Reese" Saunderson:

The artists who created Drum & Bass were clearly heavily influenced by Kevin Saunderson's House/Techno basslines, and twisted, adapted, developed them into their new sound, but does that mean that Kevin Saunderson invented Drum & Bass? Nope!
Any new genre comes about from artists being influenced by music which already exists, and then changing it, morphing it, adding their own sounds, elements and styles to it until a new creature is born. In the same way that Saunderson clearly influenced the development of Drum & bass and it's signature bassline sounds, but did not invent the genre himself, Kraftwerk clearly influenced Techno artists, but did not invent Techno themselves.
