Document examination gained legitimacy in court by showing that handwriting, ink, paper, and other document features could be analyzed using standardized, scientifically based methods. Albert S. Osborn played a pivotal role by championing rigorous procedures and publishing a foundational guide that codified how questioned documents should be analyzed and how findings should be presented in a way that courts could evaluate. His work helped establish the need for reliable methods, proper handling of exemplars, and transparent reporting, which together moved document examination from opinion to admissible scientific evidence. The other figures contributed to different areas of forensics—Locard with the general principle of trace exchange, Lattes with blood typing, and Goddard with firearms identification—making Osborn the key figure in this specific shift for document examination.
