Jan Nerger CSU

“Science has the ability to transcend boundaries to become a foundation for universal understanding.”

 — Jan Nerger, dean of the College of Natural Sciences

When Colorado State University was founded in 1870 as the Colorado Agricultural College, it had a profound mission – to provide access to education for anyone willing to attain it. While the focus of the land-grant mission was on studying “the agricultural and mechanic arts,” the natural sciences were essential to the understanding of those fields.

Foundational science classes were among some of the first offered by the school, and today they are part of the University’s core curriculum.

Physics, biology, mathematics and chemistry were fields of study harnessed to the practical applications of agricultural research at CAC. Since the establishment of the College of Natural Sciences at CSU in 1968, these disciplines have been joined by biochemistry and molecular biology, computer science, psychology and statistics as major centers of both theoretical and applied research and education for the University.

Education in the natural sciences teaches students new ways to ask questions, think critically, find answers, and solve problems. Discoveries made in the College of Natural Sciences have changed our world for the better.

For example, Melissa Reynolds, associate dean of research for the college, has developed biocompatible materials to detect and combat bacterial infections that can be integrated into medical devices for humans. Joe von Fischer, associate professor in the Department of Biology, has developed an innovative way to track invisible underground methane leaks using Google Street View cars.

Here are a few pivotal moments in the history of natural sciences at CSU.


Natural science courses were among the first classes offered at the Colorado Agricultural College


The Colorado Agricultural College was officially founded in 1870 as a land-grant college under the Morrill Act of 1862. Ten years later, in 1880, when the first classes were held, they included botany, mathematics, and natural philosophy (physics) – disciplines within natural sciences.


CSU Herbarium founded

Housed today in the Department of Biology, the CSU Herbarium holds more than 100,000 plant specimens. These meticulously collected and archived specimens serve as an invaluable documentation of the history and evolution of Colorado flora. While the herbarium is now well established, it started as a novel idea with humble roots. In 1883, botanist James Cassidy began collecting and preserving plant species from around Colorado, creating the first herbarium in the Southern Rockies. Today, the herbarium is not only an important tool for researchers, but visitors can experience what Colorado landscapes were like throughout time, including glimpses of many species that have gone extinct.

1886 – 1909

The first natural science departments are established

Math class

At the beginning of the 20th century, natural science education and research was formalized at CAC with the creation of the Department of Physics and Engineering, the Department of Mathematics, and the Department of Zoology and Entomology.


Ruth Ashton Nelson writes the original guide to flora in Rocky Mountain National Park

Rocky Mountain National Park

Ruth Ashton Nelson worked as an information clerk at Rocky Mountain National Park while she completed her master’s of science in botany at the Colorado Agricultural College. Her thesis, Plants of Rocky Mountain National Park, was published in 1933 and became the original definitive guide to flora in the park. Nelson went on to write more books on botany, including Plants of Zion National Park.


Genevieve Garst teaches the first computer science class at CSU

CSU Computer Science

In 1958, Genevieve Garst, who had degrees in mathematics and engineering from the University of Wisconsin, moved to Fort Collins to teach the first computer science class at CSU. Garst’s classes were taught more than a decade before computer science was established as a program under the Department of Mathematics at CSU. The Department of Computer Science became its own department in the College of Natural Sciences in 1974.


Franklin Graybill Statistical Laboratory established


Franklin Graybill, a professor who went on to chair the Department of Statistics, founded the Statistical Laboratory in 1961, which was later renamed to reflect Graybill’s contribution to its founding. The Franklin A. Graybill Statistical Laboratory, also known as the “stat lab,” is still in operation today. Faculty and student consultants lend their expertise in statistics to help researchers from every field of study. Learn more about the Graybill Statistical Laboratory


CSU Observatory opens


Astronomy at CSU began in 1905 with Stuart Lincoln Macdonald, head of the Department of Mathematics and Astronomy under President Barton Aylesworth, sharing the observation of space with students using a 4-inch telescope. That telescope was used for astronomy classes and research until 1965, when the new head of the department, M. Leslie Madison, opened an observatory with a 16-inch telescope. Today, students and community members can visit the Madison-MacDonald Observatory to learn more about the universe. Learn more about the Madison-MacDonald Observatory 


College of Natural Sciences is formed

The College of Science and Arts split into two colleges in 1968: the College of Natural Sciences and the College of Humanities and Social Sciences. Chemistry professor William Cook served as the first dean of the College of Natural Sciences.

1969 & 1978

Meyers Reaction and Stille Reaction

CSU Chemistry Building

The 1960s and 1970s marked an important era in chemistry at CSU with two monumental discoveries – the Meyers Reaction and the Stille Reaction. In 1969, chemistry faculty member and University Distinguished Professor Albert Meyers described the Meyers Reaction, an efficient way to make carbon bonds. Meyers went on to be elected to the National Academy of Sciences. In 1978, chemist John Stille reported the Stille Reaction, which is widely used in organic synthesis. It is largely agreed that Stille had the chance to win a Nobel Prize, but tragically was among the 111 people killed in the crash of Flight 232 in Sioux City, Iowa, in 1989.


Little Shop of Physics founded

Lsop 1990s

Known for brightly colored tie-dye t-shirts and making science fun and accessible for all ages, the Little Shop of Physics was founded in 1992. Still operating today, this hands-on science program has taken science around the world and is a cornerstone of CSU’s education and outreach mission. In February 2020, the Little Shop of Physics will hold its 29th annual open house. Learn more.


Psychology faculty member develops the driving anger scale


Department of Psychology researcher Jerry Deffenbacher developed the Driving Anger Scale in 1994. This scale helped categorize the anger felt by drivers when they are experiencing road rage. Further research by Deffenbacher found that drivers who were able to recognize their anger were able to use short-term therapy techniques, such as deep breaths, to help calm themselves.


Jennifer DeLuca is named a Pew Biomedical Scholar
