Hans Lineweaver (December 25, 1907 – June 10, 2009) was an American physical chemist, who is credited (misleadingly) with introducing the double-reciprocal plot or Lineweaver–Burk plot. The paper containing the equation was co-authored by Dr. Dean Burk, and was entitled "The Determination of Enzyme Dissociation Constants (1934)". It remains the most frequently cited paper to appear in the Journal of the American Chemical Society. Lineweaver and Burk collaborated with the eminent statistician W. Edwards Deming on the statistical analysis of their data: they used the plot for illustrating the results, not for the analysis itself.
