Below is an interactive timeline of the history of the Delaware Geological Survey, from 1951 through present, with some information about the first (albeit brief) inception of the survey back in 1837. More information can be found linked below the timeline.

|The Second Delaware Geological Survey||
The Survey started its investigations in July 1951 with Johan J. Groot as State Geologist and Lecturer, later Professor of Geology, and Louis P. Vlangas as Geological Field Assistant. The University provided office space, which was shared with the Department of Geography. The cooperative program with the USGS, begun prior to 1951, was continued. Studies of the geology of New Castle County and of the ground-water resources of the Newark area were initiated, the latter with financial support of that city.
|The First Delaware Geological Survey||
The act of 1837, created a Geological and Mineralogical Survey which was charged with investigating and mapping the various geological formations found within the boundaries of the State.
|The Delaware DataMIL is officially released||
Governor Minner officially released the Delaware DataMIL web site to the Delaware GIS community and the world.
|The Delaware DataMIL Gets a New Look!||
The Delaware DataMIL was redesigned to take advantage of more modern web technologies as well as to answer key feature requests to the system. In particular, new additions to the DataMIL include: complete FGDC metadata for all layers, a map previewer embedded into the metadata catalog, and the ability for all datasets (vector and raster) to downloaded as raw GIS data files as well as ArcIMS and WMS map services
|Sillimanite established as Delaware State Mineral||
In 1977, the Delaware General Assembly, acting on a proposal by the Delaware Mineralogical Society, established sillimanite as the Delaware State Mineral.
|Senate Bill 129 Created the Delaware Geological Survey June 4, 1951||
Governor Elbert N. Carvel promoted legislation, with regard to water resources, with Seante Bill 129 which created the Delaware Geological Survey, introduced by State Senator William O. Cubbage in the 116 General Assembly and signed into law by Governor Carvel on June 4, 1951.

|John H. Talley, Director and State Geologist (2002-2011)||
John Talley joined the DGS as a project geologist in 1972, became a senior scientist and hydrogeologist by 1986, and rose to director and state geologist by 2004. He’s consulted with dozens of university, state, and federal governments and groups and amassed a list of more than 50 publications and reports.

|Johan J. Groot, Director of DGS and State Geologist (1951 - 1969)||
In 1951, Delaware passed legislation establishing the present Delaware Geological Survey as a unit of the University of Delaware. Johan J. Groot was installed as State Geologist and Director of DGS until 1969. Groot was also Professor of Geology in the UD Department of Geology.
|James Curtis Booth was hired as the Delaware State Geologist June 1, 1837||
On June 1, 1837, James C. Booth was hired as the Delaware State Geologist at $1,200.00 a year. His field work started in the summer of 1837 and ended in fall of 1838. During the winters of 1837-38 and 1838-39, Booth analyzed samples taken. In 1839-40 he wrote "The Memoir of the Geological Survey of the State of Delaware: Including the Application of the Geological Observations to Agriculture". In Booth's "survey", published May 4,1841, he performed analyses, discussed practical applications, and the name "survey" stuck to be the name for modern research and service oriented geologic agencies.

|DGS Reinvents Itself on the Web||
The Delaware Geological Survey has unveiled a new version of their public web site. Although many of the technologies employed are consistent with modern web standards, giving the user a familiar feel and comfort level, particular attention has been paid to information and the retrieval of it. The site is designed to encourage users to explore content they wouldn't other wise read.
|DGS moves into a new building!||
The Delaware Geological Survey moves into its own home in 1989 after sharing Penny Hall with the UD Department of Geology for over 20 years.
|DGS First Drill Rig||
President of the University Of Delaware, John A. Perkins, who was an ex-officio member of the Geological Commission, requested Henry B. Du Pont to donate a small truck mounted auger drilling rig to the University for use of the Delaware Geological Survey. With wishes granted, the rig was put into operation in 1951.
|DGS Celebrates 50 Years of Service!||
On June 4, 2001 the DGS celebrated 50 years of science and service for the Diamond State. Senate Bill 129, creating the Delaware Geological Survey, was signed into law (Chapter 55, Part VI, Title 7 of the Delaware Code) by Governor Carvel on June 4, 1951.
|DGS Affiliated With College of Marine and Earth Studies||
Beginning July 1, 2008, DGS will become formally affiliated with the College of Marine and Earth Studies (CMES) within UD. DGS has been part of the University of Delaware since 1951, however, had previously reported to the vice provost for research and graduate studies.
|David R. Wunsch appointed DGS Director||
After a nationwide search, David R. Wunsch has been appointed the next Director of the Delaware Geological Survey (DGS) and Delaware State Geologist, effective Nov. 1. He will succeed John H. Talley, who retired on June 30 after more than 38 years of service. Wunsch holds a doctorate in hydrogeology from the University of Kentucky, a master’s degree in geology from the University of Akron, and a bachelor’s degree in geology, with a minor in chemistry, from the State University of New York, Oneonta. In 2011, Wunsch was elected a Fellow of the Geological Society of America. He is an Honorary Member and a past President of the Association of American State Geologists (AASG) and has previously served a term as Secretary of the American Geological Institute.
