Ed Lewis exhibited a rare combination of intellectual rigor and iconoclasm that was coupled with remarkable personal and scientific integrity and humility.

He used his prize money to establish a trust with Caltech that would go towards undergraduate scholarships when he died, saying that “Caltech has provided the kind of excellent environment that has allowed me to carry out the research that has led to the award of the Prize. . ” Undoubtedly, he had in mind the struggle that he and Jimmy had gone through to attend college during the Depression. More than anything else, however, Ed derived pleasure from returning to his beloved flies, through which he conducted his daily dialogue with the laws of nature.

Furthermore, the discovery of transcription 34 Genes factors that regulate the expression of nuclear genes was many years away. ” For example, he postulates the following reaction series: S bx+ −−−→ A Bxl + −−−→ B bxd + −−−→ C In words, substrate S is converted to product A by the bx+ gene product, A is converted to B by the action of the Bxl + gene product, and B is then converted to C by the bxd + gene product. In terms of “levels of development,” then: A or B −−−→ L-ms L-mt C −−−→ L-ab. In words, substances A or B are able to convert the level of development of a particular segment from mesothoracic (second thoracic) to metathoracic (third thoracic) in identity, while substance C promotes the next level of development, abdominal identity.
