To pay tribute to the first author, J. Whitridge Williams, we begin each chapter with a passage from his 1st edition that complements the topic. During this selection process, we were inspired by the strides that modern obstetrics has made since that edition in 1903. Similarly, we were humbled by some of the classic challenges that still persist. Preterm labor, preeclampsia, and infections are some examples. That said, many of these advances were derived from rigorous, evidence-based research. And, we acknowledge and support the power of this academic ideal to further our specialty in the decades to come.
