Watson and Crick used data from X-Ray crystalography as well as theoretical models on 3-D configuation of nucleic acids to deduce the structure of DNA.

Watson and Crick did not discover DNA - it had been isolated, then called nuclein, in 1869. What remained unknown was the structure of DNA - this is what Watson and Crick proposed. After they came up with a structure for DNA (1953), they went to 'The Eagle' pub in Cambridge, just round the corner from their lab, and Crick announced to the other customers that he and Watson had discovered 'the secret of life'. The Eagle now has a plaque commemorating the event. They also wrote a letter to Nature, though presumably not while at the pub. Watson and Crick did not discover DNA. What they did was examine the data collected by others, and propose a structure for the DNA molecule.

The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.

He didn't. DNA was already known before Crick, Watson, Wilkins and Franklin discovered its chemical structure in the early 50s. Crick and Watson published in "Nature" in April of 1953.
