Lafayette Instrument Co. Announces the Completion of the Cleve Backster Special Collection

Cleve's decades of research are now archived and accessible to the public.

Lafayette, IN, June 17, 2019 - Lafayette Instrument Company (LIC) today announced the completion of the Cleve Backster papers Special Collection at the University of West Georgia.

Cleve Backster was a renowned biocommunication researcher, polygraph examiner, and educator. After he passed away on June 24, 2013, Lafayette Instrument was honored to become the caretaker of his life’s work. However, Lafayette Instrument’s warehouse is not ideally suited for archiving or searching documents.

In 2018, Lafayette Instrument had the good fortune of being introduced to Blynne Olivieri, Head of Special Collections and Associate Professor at the University of West Georgia. Ms. Olivieri indicated the Backster papers would complement others at the University and she agreed to visit LIC to sort and pack the files so they could be well-preserved and eventually accessible to others.

Nearly 8 months after collecting the materials from Lafayette, Indiana, Ms. Olivieri contacted LIC because the indexing of the 46 boxes of files is complete and the Index can be found here:

"UWG's Special Collections is open for use by anyone. We have scholars, faculty members, students, and members of the general public use our collections.

We have massive psychology collections, both archival collections and printed materials, particularly pertaining to humanistic & parapsychology. The great thing is the intersections - for example, we have Stanley Krippner's papers who corresponded with Cleve Backster.

We have secure, temperature & humidity-controlled storage, and use acid-free containers to ensure the longtime preservation of the materials."
-Blynne Olivieri, University of West Georgia

At the end of another year, we would like to share some interesting things about the history of Lafayette Instrument and a couple of special anniversaries.

Lafayette Instrument Company was established in 1947 with one employee and an 8 x 10 foot shed for a workshop. That one employee was our founder, Max Wastl. Max was a German immigrant who studied Electrical Engineering at Purdue University.

The first catalog was printed in 1954, and a message on the front read, in part:
"We are always open to constructive criticism and suggestions from our customers. It is our aim to build instruments of high quality and at a reasonable cost."
-Max Wastl

Through Max's leadership and with this goal in mind, Lafayette Instrument quickly became the market leader in psychophysiological instrumentation for schools and university laboratories. As a result, sales growth required multiple expansions to accommodate new products and employees.

A smart and capable young man named Tom Smith joined the company in 1967, and he would later become the longest tenured employee in the company's history.

In 1972, expertise in physiological testing was used to produce Lafayette's first polygraph instrument. Since then, Lafayette Instrument has been the world's leading manufacturer of Polygraph instrumentation and equipment, having distributed more credibility assessment instruments to private examiners, government, and military organizations around the world than any other manufacturer.

Lafayette Instrument acquired Campden Instruments in the United Kingdom in 1998. Campden serves as a dedicated European office and has incorporated complementary products into the exisiting life sciences product line. Campden has continued to provide expertise in the growing neuroscience research markets.

September 2016 brought the honor of being named the "Greater Lafayette Commerce Small Business of the Month." Lafayette Instrument is thankful for the award and the recognition from the community.

During 2016-2017 alone, Lafayette Instrument supported customers from over 80 countries and every US state. The company is proud to celebrate this accomplishment and 70 years of operation in 2017.

Lafayette Instrument would also like to congratulate that young man, Tom Smith, who started in 1967 on his 50 YEAR ANNIVERSARY with the company; it is a remarkable accomplishment and a blessing. The company is proud of its history and looks forward to many more years of growth locally and around the world.

The Vice President of Lafayette Instrument Company's (LIC's) Polygraph Division, Chris Fausett, will be retiring on March 4th, 2016 after 33 years with the company. During his tenure, Chris helped to propel the company to the forefront of polygraph instrumentation manufacturing. He gave generously of his time and resources to help educate examiners and bolster the profession as a whole. Chris' commitment is further demonstrated by his curation of dozens of polygraph historical artifacts, many of which are on display at the company's headquarters. With guidance from Chris, Lafayette Instrument company has been able to partner with 43 representatives and dealers, selling to 80 countries around the world.

Chris and the management team have a very strong polygraph sales and support group, and they have worked for two years on the succession plan for this division to ensure continuity and quality of service.

Chris' successor is Steve Rider. Steve is the son of longtime LIC President, Roger McClellan.

Steve is currently the Service, Polygraph Sales, and IT Manager; he will be promoted to Vice President, effective March 7th, 2016. Steve's military background with the United States Marine Corps and his 16 years of technology leadership experience make him the ideal candidate for this position.

Lafayette Instrument Co. Announces Operational and Product Updates

New systems and products prepare LIC and customers for the future.

Lafayette, IN, December 30, 2015 - Lafayette Instrument Company (LIC) today announced equipment purchases made in 2015 to improve product quality and operational efficiency. These purchases include a 3D printer for making prototypes and small plastic parts, a flatbed UV LED printer to replace screen printing, and a Vapor Phase Soldering Oven to replace an older model.

The 3D printer allows LIC to prototype quickly and iterate on design ideas without waiting on materials or components from third party providers. The new UV LED printer allows greater speed, precision, and variety of printing. The finished product is also very durable. And finally, the new soldering oven is faster, more accurate, and it provides more even temperature distribution. All of the new equipment helps to ensure higher quality products while keeping the cost of manufacturing down. These investments show that while the company is nearly 69 years old, it is still an industry leader in terms of using the best and most current technology available.

Additionally, the company has undergone security updates, facility updates and reorganization to prepare for the new year, new customers, and new products as well as providing optimal support for existing customers and products.

In the first half of the year, Lafayette Instrument Company introduced Scurry Activity Monitoring Systems for Neuroscience and PI-DAS as a new credibility assessment tool in the Polygraph product line. In the second half of the year, LIC began making improvements to their various websites to make online ordering easier and the mobile experience better. This work will continue into the first half of 2016. New partnerships are also underway to develop custom product solutions, greater distribution of existing products and to bring new products to market in 2016.

The executive management team is very pleased to be able to reinvest in the great company in support of its mission to "Deliver robust and effective customer-driven instrumentation and software solutions to enable data collection and analysis."
