Dr. Richard A. Williamson, DDS, MS, FICD, FACP, a Board-Certified Prosthodontist and dental expert witness with over 46 years of experience, has been featured in the 2026 Expert Witness Guide of Arizona Attorney Magazine, the official publication of the State Bar of Arizona. His article Lessons from Lincoln’s Legacy, co-authored with Sameer S. Somal, examines how Abraham Lincoln’s legal principles remain deeply relevant to expert witnesses and attorneys practicing today.
Lincoln, NE (PRUnderground) July 28th, 2026
Lessons from Lincoln’s Legacy draws a thorough line between Lincoln’s courtroom habits and the standards modern expert witnesses are held to. Dr. Williamson highlights how Lincoln’s reputation for honesty, his calm under adversarial pressure, and his disciplined approach to preparation translate directly into best practices for expert witness work.
Along with his co-author, Sameer S. Somal, Dr. Williamson draws on key moments from Lincoln’s legal career to illustrate what sets a great expert witness apart. Lincoln’s refusal to take on cases he found ethically indefensible, even when they were legally winnable, for instance, speaks directly to the importance of selective engagement. Dr. Williamson applies that same standard to expert witness practices. He also drew lessons from Lincoln’s defense of Duff Armstrong in the 1859 Harrison murder trial, taking it to express the importance of preparation and fact-based rebuttal.
In between each anecdote, one conclusion rings true. Lincoln’s ability to make complex arguments accessible to ordinary people is a skill Dr. Williamson argues is just as critical in the courtroom today. Clear, plain communication, without sacrificing accuracy, is what separates good testimony from one that is great.
