Dr. Nathan Isgur, born 1947 in South Houston, Texas, remained in residence of his home town through the completion of his high school education. He later studied at the California Institute of Technology where he received his B.S. in physics in 1968. He began his doctoral program at the University of California, Berkley soon after, but chose to transfer to the University of Toronto to continue his graduate studies after having failed to receive a draft deferment.1 Dr. Isgur received his Ph.D. in Particle Theory in 1974. He served as a professor of physics at the University of Toronto from 1976 to 1990.
In 1990, he began his work at CEBAF (Continuous Electron Beam Accelerator Facility), later known as the Thomas Jefferson National Accelerator Facility2 serving as the Lab's Theory Group Leader. He was also on the faculty at the College of William & Mary in Williamsburg, Virginia as a Governor's Distinguished Professor. Dr. Isgur, a leading theoretical physicist, was formally named Chief Scientist in 1996, which he held until his untimely death in 2001. In this role, Dr. Isgur advised the Lab's Director on the planning and interpretation of the Jefferson Lab experimental program and served on the Lab's Director's Council.2
During his career, Dr. Isgur published over 100 papers on the quark structure of matter and was well known for his work on the excited states of the proton.2 In 1978, he and Gabriel Karl proposed the 3-quark model that is now the standard model of the proton and neutron. 3 Dr. Isgur's work with Mark Wise led to the discovery of heavy quark symmetry in chromodynamics.2
Dr. Isgur's work earned him a number of awards, including the Steacie Price (1986), the Herzberg Medal (1984), the Rutherford Medal (1989)3, and the Sakurai Prize (2001). Dr. Isgur was married to Karin Bergsagel, with whom he had two sons.
He died in 2001 of complications from multiple myeloma.

This collection primarily consists of materials related to Dr. Isgur's work at Jefferson Lab, though also including some records from his earlier work at the University of Toronto. The bulk of the collection consists of Dr. Isgur's publications and research notes, most of which are handwritten and undated. Also included are correspondence, drafts of Dr. Isgur's writings, as well as published articles that contain notes and editorial comments. The collection also consists of material from the many conferences and lectures that Dr. Isgur attended including notes, transparencies*, lecture and presentation outlines and related material.
*Transparencies of presentations at conferences/seminars/workshops have been digitized. Hard copies are available in the Archives; digital access available upon request.
Series I: Notes. Included in this series are notes by Dr. Isgur; some in collaboration with colleagues. There are many unlabeled and undated notes, and those are in their own sub-series. Any collaboration correspondences in reference to the sub-series of this group are included in the category in which they were found when the collection was accessioned.*
- Sub-series A: QCD & P. Geiger
- Sub-series B: Scalar Mesons
- Sub-series C: Multiquark Hadrons
- Sub-series D: Baryons
- Sub-series E: Known Subjects by date
- Sub-series F: Undated
- Sub-subseries i: Labelled Topics
- Sub-subseries ii: Unlabeled Topics
Series II: Publications. Included in this series are drafts, correspondence, revisions, and notes for published copies of papers written for journals and proceedings of conferences Dr. Isgur attended. This collection is in chronological order, as best as could be deciphered. Those without dates are at the end of the given series. A master list is within the collection.
Series III: Correspondence. This series is inclusive of various correspondences of Dr. Isgur not relating to a specific project.
Series IV: Educational Course Materials. These papers appear to have been used by Dr. Isgur as a student and as a professor. This series has a large digital facet.
Series V: Miscellany. This series covers articles written about Dr. Isgur, articles he refereed, and various notes and information regarding various facets of Jefferson Lab.
Series VI: Presentations/Lectures. This series is subdivided into two subseries: dated and undated. The undated series is arranged alphabetically by the lecture title.
- Sub-series A: Dated
- Sub-series B: Not Dated
*Records are arranged chronologically by date of creation within each series. If the date is unknown, records are grouped by topic. For records lacking date and title, they are in the original, unsorted order.
