Erik Ellestad did all the hard work to bring this application to life. I imagine that he knows more about the Savoy Cocktails than anyone alive today. He is currently working his way through all the Savoy Cocktails in a project he calls "Stomping through the Savoy."
David Wondrich has collated the recipes in the Savoy list against other cocktail books he suspects Harry Craddock (and his editors) used as source material.
Thanks also go to Hugo Ensslin, Robert Vermiere, Judge Jr., Harry McElhone, Patrick Gavin Duffy, Jerry Thomas and Harry Johnson for collecting these recipes and putting them in print in the first place.
I take credit only for the errors that have crept into the source material through my rough handling. For that I apologize.
