John Robert McNeill is a prominent American environmental historian and professor. He is widely recognized for pioneering the study of environmental history. This field examines the complex relationships between human societies and the natural world. McNeill currently teaches at Georgetown University in Washington, D.C. He works within both the History Department and the Walsh School of Foreign Service. His research explores how human actions have reshaped the Earth's ecosystems over time.

McNeill's academic journey began in Chicago, Illinois, where he was born on October 6, 1954. He attended the University of Chicago Laboratory Schools during his early education. He later earned a BA from Swarthmore College in 1975. He continued his studies at Duke University to earn an MA in 1977 and a PhD in 1981. In 1985, he joined the faculty at Georgetown University. He eventually became a University Professor in 2006. He also held the Cinco Hermanos Chair in Environmental History and International Affairs.

One of McNeill's most significant contributions is his book, "Something New Under the Sun," published in 2000. This work provides an environmental history of the twentieth-century world. He argues that human activity caused environmental changes on an unprecedented scale during this century. While humans changed environments before 1900, the scale of change was much smaller. McNeill identifies several key drivers for this modern shift. These include the use of fossil fuels, rapid population growth, technological changes, and international political pressures.

McNeill also explores how ecology influences political power and warfare. In 2010, he published "Mosquito Empires: Ecology and War in the Greater Caribbean, 1620–1914." This book examines the Caribbean region over nearly three centuries. He explains how the transition to a sugar plantation economy changed the local ecology. These ecological shifts increased the presence of mosquito-borne diseases, such as malaria and yellow fever. McNeill notes that "differential resistance" between local and European populations shaped Caribbean history. This biological factor helped Spain protect its colonies from European rivals for a long period. It also played a role in why empires like Spain, France, and Britain lost their mainland American territories during revolutionary wars.

In 2016, McNeill co-authored a book with Peter Engelke titled "The Great Acceleration." This work focuses on the Anthropocene, which is a proposed era of intense human interference in Earth's ecology. The term "Great Acceleration" describes the rapid increase in human impact seen since 1945. This period marks a distinct stage in how humans interact with the planet's systems. McNeill's work helps define this era by tracing the causes of rapid environmental change.

Throughout his career, McNeill has received numerous prestigious honors and awards. He has been a recipient of a MacArthur Grant and a Guggenheim fellowship. He also held two Fulbright Awards and a fellowship at the Woodrow Wilson Center. His books have won several major prizes, including the World History Association Book Prize and the Toynbee Prize. In 2010, "Mosquito Empires" won the AHA Beveridge Award and a PROSE award. He was elected to the American Academy of Arts and Sciences in 2017. In 2018, he received the Heineken Prize in History from the Royal Netherlands Academy of Arts and Sciences.

McNeill has also held significant leadership roles in the historical community. He served as the president of the American Society for Environmental History from 2011 to 2013. He was also a Vice President of the American Historical Association from 2012 to 2015. In 2019, he served as the president of the American Historical Association. He has written seven books and has edited or co-edited 17 others. His diverse body of work, including the textbook "The Webs of Humankind," continues to shape how we understand global history. He is currently researching the environmental history of the Industrial Revolution.
