Papers of two dentists: Ziesel, who developed a technique and instruments for treating pyorrhea, and Darby, a founder of the University of Pennsylvania Dental School.
Included are articles, speeches, lectures, correspondence, unidentified photographs; an autograph book of attendees at testimonial dinner for Darby, dinner menus and programs; copies of journal entitled The Dental Cosmos, with articles by Ziesel; notebook of an unidentified dentist with names of patients, including Mr. and Mrs. Henry Adams; notebook presumably belonging to Lt. Cmdr. G. R. Bevan.The papers are largely mementoes of several occasions on which Dr. Darby was honored. They also include a record of the practice of an unnamed dentist that began in May 1885. The collection contains speeches and articles in which Ziesel describes his surgical techniques and instruments used in pyorrhea treatment. The series begins in 1919 when he asked the National Dental Association to allow him to speak at its annual convention, but his proposal was late and he was refused. It encompasses his disagreements with entrenched traditionalists, correspondence with many dentists interested in copying technique, work with patients referred for surgery, and his attempts to have this surgery made part of dental school curriculum.
Divided into 2 series

Biographical / Historical:
Dr. William Ziesel, who developed a surgical technique to eliminate pyorrhea, practiced dentistry in Philadelphia. This collection contains Dr. Ziesel's speeches and articles. In these he describes his surgical techniques and the instruments he used in pyorrhea treatment. The collection begins in 1919 when Dr. Ziesel asked the National Dental Association to allow him to be on the program of its annual convention although he was late in so requesting and he was refused. It encompasses his disagreements with the entrenched traditionalists, his correspondence with many dentists interested in copying his technique, his work with patients referred to him for this surgery, and his attempts to have this surgery made part of dental school curriculum.
Dr. Edwin Tyler Darby was one of the founders of the dental school at the University of Pennsylvania where he was a professor of operative dentistry from 1878 to 1926. He was Emeritus Professor for five years. An attempt was made to set up a Chair of Operative Dentistry in his name. Dr. Ziesel referred to Dr. Darby as a supporter of his methods to eliminate pyorrhea. The papers are largely mementos of several occasions on which Dr. Darby was honored. They also include a record of the practice of an unnamed dentist that began in May 1885.

Series 10, Dupont Case Study, 1978-1984, contains correspondence, data, notes, reports, research, and visual aids concerning one of the many American companies where Mundel consulted. Dupont was selected because of its prominence in the American business world.
Series 11, Films and Videos, circa 1939-1973, is comprised of 16mm films and 1⁄2" VHS videocassette tapes. The bulk of the series is 16mm films. The films relate to the documents in Series 6: Time and Motion Studies. There are six subseries: Rating Films, 1939-1973; Memomotion Films, circa 1948-1959; Multi-Image Loops, circa, 1956-1958; Instructional Films, circa 1939-1962; Travel Films, circa 1955-1958 and Papers, undated.
Films are labeled either OF, RF, OV, or RV, for Original Film, Reference Film, Original Video, and Reference Video, respectively. [Example: For "676.24 OF Roll Edge on Sheet Metal Disc, circa 1960 (REF. FILM 676.24 and REF. VIDEO 676.70)," 676 is the collection number; 24 is the item number; OF means original film; "Roll Edge on Sheet Metal Disc" is the title; 1960 is the date followed by any reference copies. In this case there are both a reference film and a reference video. The Archives Center will eventually have reference copies for all of the films. for researchers to view.
Subseries 1, Rating Films, circa 1939-1973, represents Mundel's work with rating or pace films. This technique films a worker doing a repetitive work unit and allows trained motion study analysts to establish time standards. These films show a wide variety of jobs held by both men and women, American workers and Japanese workers. There are three groups of films:
Demonstration Rating Films: These films have the same format as titles with 10 scenes of workers doing a work unit at different paces. The films are arranged according to Mundel's numerical system and retain the original titles. These films should be projected at 1000 frames per minute.
Poultry Rating Films: These are rating films that Mundel did for the USDA and the Consumer Protection Programs.
Miscellaneous Films: These are Mundel's rating films for Tung Sol, ASF, Woods Veterans Hospital, and Montfort. There is also a rating film taken by an English company.
Subseries 2, Memomotion Films, circa 1948-1959, includes memomotion examples that were incorporated into instructional films. Memomotion is a filming technique created by Mundel. Time and motion analysts film a non-repetitive or extended crew activity at one frame per second and then project the film at normal speed. In this manner, the analyst can record a longer work period at a fraction of the cost and be able to analyze the film much more quickly. Memomotion is often used in conjunction with work flow diagrams.
Subseries 3, Multi-Image Loops, circa 1956-1958, combines seven of Mundel's multi-image loops onto one film core. The films display twelve images of rating films at the same time. The worker in each image is working at a different pace (fastest in the top left-hand corner and the slowest in the bottom right-hand corner). Time and motion study analysts could watch the loops for as long as they needed to get an idea of what the range of paces for a certain job could be. The loops were disassembled and spliced together for preservation and viewing purposes.
Subseries 4, Instructional Films, circa 1939-1962, includes Mundel's attempts to educate others about his filming techniques and overall industrial engineering themes. The films teach ways to improve productivity through motion studies, how to make memomotion films, and the College of Technology, Birmingham, England's method of making microscope slides.
Subseries 5, Travel Films, circa 1955-1958, includes films that combine Mundel's love for travel and different cultures with film documentation of Japanese seminars.
Subseries 6, Papers, undated, contains papers directly related to the films. Of importance are the rating sheets which associate different percentages of efficiency to the paces in the film.
This collection is divided into eleven series.

Biographical / Historical:
Marvin Everett Mundel, born April 20, 1916, was a major figure in the fields of industrial engineering and time and motion studies. He is known particularly for his consulting work, seminars and teaching, as well as numerous publications based on his expertise in work management and productivity enhancement. He began his engineering career in 1936 with a B.S. in Mechanical Engineering from New York University (1936), followed by an M.S. and Ph.D. in Industrial Engineering earned in 1938 and 1939, respectively, from the State University of Iowa.
In the late 1930s and 1940s, work measurement studies were considered the state-of-the-art method for improving industrial production. Mundel continued and built upon the achievements of pioneers Frank and Lillian Gilbreth during his teaching career at both Bradley and Purdue Universities. He also conducted seminars at Marquette University Management Center and the University of Wisconsin's Extension Center in Milwaukee. In addition to his American teaching career, Mundel was a visiting professor at both the University of Birmingham in England and Keio University in Tokyo, Japan.
In 1952, Mundel started a consulting firm which aided corporations and governments in either work measurement consulting or, later in his career, industrial engineering consulting. His first clients were United States government agencies that wanted to gain control over lost revenue or manpower. His position from 1952 to 1953 at the Rock Island Arsenal in Illinois, as the first Director of the Army Management Engineering Training Program, transformed management techniques in the Army.
After his employment at Rock Island, Mundel began a series of consultant roles with corporations eager to standardize labor practices and make production more efficient. From 1953 to 1963, Mundel conducted time and motion studies at various manufacturing companies and developed techniques to measure work units. His most important contribution to the field of time and motion study was the development of memomotion, a stop-action filming technique used to determine time standards for work tasks.
Following his refinements of time and motion study, Mundel took his expertise to Japan where he offered his consultant services to various Japanese manufacturing firms during the 1960s. His interests evolved from time and motion studies to include work management and overall management organization consulting. During the 1960s and 1970s, Mundel also returned to government consulting in the United States with these new techniques, in offices such as the Bureau of the Budget and United States Department of Agriculture. This period marked an important evolution in Mundel's career, from time and motion study to work measurement and then to industrial consulting. Mundel was among the first consultants to export American management techniques to Japan, and, in his later career, to other Asian countries. He became an integral part of the Asian Productivity Organization, a group that helped developing Asian countries learn how to increase productivity. His seminars sought to provide corporations and governments with efficient management techniques so that Asia would become a strong economic center. Mundel was sensitive to cultural differences as well as varied methods of management and standards of productivity.
Mundel won the Gilbreth Award in 1982. He continued conducting seminars and writing books and articles well into the 1980s, until failing health prevented him from traveling. When Mundel died in 1996, he was well respected in the field of industrial engineering for his many contributions.
