No. DNA wasn't "invented", it's a naturally occurring substance that's been around about as long as life on Earth has been around. They didn't even "discover" it; by the time they were working on it, it had been known for about 100 years. What they did (with a great deal of largely-unacknowleged-at-the-time help from Rosalind Franklin) was figure out the molecular structure.
James Watson,working with Francis Crick and Rosalind Franklin discovered the shape of the DNA molecule.
Watson and Crick's model of DNA showed a double helix.
Watson and Crick's model of DNA showed a double helix.
The two scientists to establish DNA are James Watson and Francis Crick.

The company Watson and Crick are famous for discovering the DNA Double Helix. Watson and Crick won the Nobel Prize in 1962 for their work with the DNA Double Helix.
Crick and Watson tried to understand the structure of DNA by building three dimensional models of the molecule.
Watson and Crick proposed the double helix model of the DNA structure in 1953.
