A Detailed History of the Illinois Natural History Survey

Since 1858 the Illinois Natural History Survey (INHS) has been the guardian and recorder of the biological resources of Illinois-the state’s biological memory. With a staff of over 200 scientists and technicians, it is recognized as one of the premier natural history surveys in the nation. Over the years, its mission has remained fairly constant: to investigate the diversity, life histories, and ecology of the plants and animals of the state; to publish research results so that those resources can be managed wisely; and to provide information to the public in order to foster an understanding and appreciation of our natural heritage.

Stephen Forbes was the first director of the INHS, and to him the word survey meant more than a censusing of organisms or publishing lists showing their distribution. Forbes felt that any study should define the relationships among living organisms and their environment-an ecological survey. This theory prevailed in his work and underlined the early research done at the Natural History Survey. In 1880 Forbes stated, “The first indispensable requisite is a thorough knowledge of the natural order-an intelligently conducted natural history survey. Without the general knowledge which such a survey would give us, all our measures must be empirical, temporary, uncertain, and often dangerous.” Many components make up the INHS. Its research, collections, publications, long-term studies, field stations, and educational outreach have not only made the Illinois Natural History Survey the largest, but also the most successful state biological survey in the country.First home of the Illinois Natural History Survey, Normal, IL

1858 On June 30, the State Natural History Society of Illinois is organized and housed at Illinois State Normal University.

1860 The earliest insect specimen in the INHS Insect Collection is contributed by Benjamin D. Walsh.

1861 The society is legally chartered by the state legislature on February 22, and a library is provided.

1861 The society’s museum is officially dedicated on Christmas Day. Of the museum, theBloomington Pantagraph writes: “It has been said that he who places a valuable truth or fact within the reach of all, is more worthy than he who discovers it.” The museum contains 60,000 specimens.
