Dr. Walter McCrone's contributions to microscopy workshops and the certification of criminalists

Walter McCrone was not only a remarkable forensic microscopist, but also a skilled grants man and devoted scientific professional. This article briefly recounts his activities in the 1970s and 80s where he played a major role in securing grant funds to sponsor microscopy training around the country, and in using his considerable professional influence to advance the cause of certification.     

Dr. Walter C. McCrone's contribution to the characterization and identification of explosives

Dr. McCrone was an amazing individual, possessing many talents and having many interests. He especially loved applying polarized light microscopy (PLM) to answering the question-at-hand and solving problems. He applied PLM to many different fields including the identification of air pollution particles, asbestos identification, art conservation, pharmaceuticals, industry problems and forensic sciences. A field that I believe he enjoyed the most was the characterization and identification of explosives. Throughout his life he worked on, gave presentations and published articles on the characterization and identification of explosives. Also, he encouraged other scientists to give presentations and publish on the subject by providing "behind the scene" advice and/or be a co-author on a paper. He unselfishly taught others how to apply PLM and incorporate this invaluable tool into their analytical scheme.     

Remembering Walter C. McCrone--scientist, mentor, leader and friend

Walter C. McCrone (1916-2002) was a special person. While books, journals and ledgers record over 400 of his technical contributions, his true legacy is his inspiration and leadership. In remembering "Doc" McCrone, we honor a man dedicated to people, to science and to education. His passion for microscopy was only exceeded by his love of science, people and teaching. While he ranked microscopy as the first step in every scientific investigation he made use of all technologies in formulating and testing hypotheses. Everyone who met Walter has a story to tell of this man's impact on his or her life; I will tell you mine.     

Genetic and environmental contributions to stability and change in levels of self-control

Purpose

There has been an emerging body of research estimating the stability in levels of self-control across different sections of the life course. At the same time, some of this research has attempted to examine the factors that account for both stability and change in levels of self-control. Missing from much of this research is a concerted focus on the genetic and environmental architecture of stability and change in self-control.

Methods

The current study was designed to address this issue by analyzing a sample of kinship pairs drawn from the Child and Young Adult Supplement of the National Longitudinal Survey of Youth 1979 (CNLSY).

Results

Analyses of these data revealed that genetic factors accounted for between 74 and 92 percent of the stability in self-control and between 78 and 89 percent of the change in self-control. Shared and nonshared environmental factors explained the rest of the stability and change in levels of self-control.

Conclusions

A combination of genetic and environmental influences is responsible for the stability and change in levels of self-control over time.     

Dr. McCrone's teaching methods in forensic microscopy, their nature, history, and durability

The microscopy teaching activities of Walter C. McCrone started long before the McCrone Research Institute (McRI) was incorporated as a not-for-profit research institute in Chicago. McCrone obtained his first microscopy training at Cornell University, with Emile Monnin Chamot, and was shortly thereafter appointed a full instructor in chemical microscopy before obtaining his Ph.D. (in 1941). After leaving Cornell, he had classes at the Armour Research Foundation (now Illinois Institute of Technology Research Institute--IITRI) from 1942-1956 and founded McRI in 1960. The course and student totals from McCrone's educational activities are impressive. As of January, 1, 2002, the cumulative for McRI (1942-2002) is 2,130 courses for 22,557 students. There has been an average of 600 students in an average of 60 classes for the last several years. Nearly all of the courses contain one week of intensive hands-on microscopy training with usually only one instructor for the entire duration of the class, making it a unique teaching experience for both student and Instructor. Thousands of students have successfully completed at least one of McCrone's specialized forensic microscopy (trace evidence) courses and the number will steadily increase as a result of McRI's continued efforts to interest forensic investigators in microscopy.     

A tribute to Dr. Ellis R. Kerley: the Kansas years.

Dr. Ellis R. Kerley, one of the founders of the Physical Anthropology section of the American Academy of Forensic Sciences, was born in Kentucky and received his undergraduate degree at the University of Kentucky. Following the completion of his doctoral degree (University of Michigan) he was a visiting professor at the University of Kentucky before joining the faculty at the University of Kansas in 1966. At Kansas he was a major advisor for many graduate students who were to become leaders in the new area of Forensic Anthropology.     

Dr. T. Dale Stewart's travels

Renowned forensic physical anthropologist Dr. T. Dale Stewart traveled extensively to countries all over the world. The reasons for his journeys were manifold. He did fieldwork, took part in congresses, visited scientific institutions, and lectured by invitation at various universities. This paper deals with his journeys in general and with his four visits to Czechoslovakia in particular. Three of them were undertaken in connection with scientific congresses dedicated to Dr. Ales Hrdlicka. Dr. Stewart, as Hrdlicka's successor in the Smithsonian Institution, always chose an appropriate topic for his lecture. His visits to Hrdlicka's native country and town contributed to better mutual understanding and exchange of ideas between physical anthropologists and anatomists from both countries, the USA and Czechoslovakia (the today separate Czech and Slovak Republics).     

Saleem Shah's contributions to forensic clinical assessment

This article describes Saleem Shah's vision for specialized methods that were needed to perform more reliable and valid forensic clinical assessments. He contributed to their development by his consultantion and support as Director of the Center for Studies of Crime and Delinquency at NIMH, and the played a major role in their implementation in forensic mental health systems nationwide.
