Discovered use of ethylene gas as an anesthetic

In 1923, University of Chicago physiologist Arno B. Luckhardt, SB 1906, PhD 1911, MD 1912, discovered the anesthetic use of ethylene gas. In the 20 years following his discovery, ethylene came into general use as an anesthetic in major operations.

Proved that an Ice Age flood shaped the Scablands in Washington State

In a 1923 paper, UChicago geologist J. Harlen Bretz, PhD 1913, theorized that unique geologic features in the state of Washington were the product of a cataclysmic flood. It wasn’t until four decades later that his theory was widely accepted. Bretz received the Penrose Medal from the Geological Society of America in 1979. In 2009, the US government passed legislation to create the Ice Age Floods National Geologic Trail, the first such trail in the United States.

Discovered the universe is expanding

Created forerunner of Black History Month

Known as the father of black history, historian Carter G. Woodson, AB 1908, AM 1908, announced the creation of Negro History Week at the Wabash YMCA in Bronzeville in February 1926. Negro History Week was the forerunner of the nation’s annual commemoration of Black History Month, established in 1976. Woodson helped to transform how people think about black history, creating the peer-reviewed Journal of Negro History, establishing the Association for the Study of African American Life and History (ASALH), and starting the ASALH Press.

1928

Ernest Burgess, Professor in Sociology

Inspired the field of urban sociology

With The Ghetto (1928) and Urbanism as a Way of Life (1939), sociologist Louis Wirth proposed a new academic paradigm for city life as a sociological construct, which was central to the establishment of urban sociology as a field of study. Wirth’s contributions, along with groundbreaking research by sociologists Ernest Burgess and Robert Park, provided the foundation for the Chicago School of Sociology, which emerged in the 1920s and 1930s. University researchers explored the urban environment by combining theory and ethnographic fieldwork in Chicago; this approach is now applied to many other urban areas.

1928

Published the first business-focused scholarly journal

Founded in 1928 and published by the University of Chicago Press, the Journal of Business is believed to be one of the first scholarly journals to highlight business-themed research. The journal—which ceased publication in 2006—covered business finance and investment, money and banking, marketing, international trade and finance, and administration.
