Luria/Delbruck ran a number of classic experiments on the existence of useful mutations BEFORE they are needed.    From Wordnik.com.  [Another predictable argument against front-loading] Reference

We learned about Luria-Delbruck and the evidence that mutation was random, ribozymes and the RNA world, Hardy-Weinberg and the rest of population genetics.    From Wordnik.com.  [Why Do So Many Doctors Accept Evolution? - The Panda's Thumb] Reference

Recent advances in this field reveal mechanisms by which a specific stress does in fact cause mutations in related genes, thus resolving the issue raised by Delbruck.    From Wordnik.com.  [Analogy, How Scientifically Powerful is It?] Reference

As already understood by Delbruck (1971), Aristotle's concept of the eidos, in the context of ontogenetic development, is in some respects remarkably similar to the modern concept of the genetic program.    From Wordnik.com.  [Against Darwinism] Reference

The search for directed mutations has been stymied by the problem posed by Delbruck in (1946): if a mutation can only be observed under conditions that may cause it, as well as select it, how can we tell the difference?.    From Wordnik.com.  [Analogy, How Scientifically Powerful is It?] Reference

As regards the evidence of the randomness of mutation that I am supposedly being asked for; my very first responce to Irving pointed him the the Luria-Delbruck experiment which showed that mutations in the experiment were random with respect to adaptive advantage; and to a review article by Lenski detailing experiments that had (probably) demonstrated the consistency of "adaptive mutation" with Darwinian mechanisms.    From Wordnik.com.  [Clear Thinking?] Reference

I am convinced that Delbruck made a great tactical mistake on behalf of the German Government when he imposed this prohibition against export of goods to America.    From Wordnik.com.  [My Four Years in Germany]

When Delbruck finally gave a permit for the export of four thousand tons more of cyanide, the psychological moment had passed and we could not obtain through our State Department a pass from the British.    From Wordnik.com.  [My Four Years in Germany]

Among the signers of this reasonable men's petition were Prince Hatzfeld (Duke of Trachenberg) head of the Red Cross, Dernburg, Prince Henkel Donnersmarck, Professor Delbruck, von Harnack and many others.    From Wordnik.com.  [My Four Years in Germany]

The German Vice-Chancellor and head of the Department of the Interior, Delbruck, put an export prohibition on cyanide early in the war; and most pigheadedly and obstinately claimed that cyanide was manufactured nowhere but in Germany, and that, therefore, if he allowed cyanide to leave Germany for the United States or Mexico the English would capture it and would use it to work South African mines, thus adding to the stock of gold and power in war of the British Empire.    From Wordnik.com.  [My Four Years in Germany]
