David Haas received his BA in Physics and PhD in Biophysics in protein crystallography and molecular biology at the State University of NY at Buffalo.  For the next five years, he performed basic research in protein crystallography at several institutions in Europe, Israel and the United States.  In 1970, he joined Philips Electronic Instruments in Mt Vernon NY as Principal Scientist for X-ray systems, working on analytical instruments and designing some of the first airport security X-ray systems that were used worldwide during the 1970s.  Conceiving the idea of a self-expiring security ID (color-changing Visitor badges), David and his wife, Sandra, formed Temtec Inc. which developed and manufactured high-tech visitor and temporary IDs for more than 20 years under the brand name TEMPbadge.  Temtec Inc. was sold to Brady Worldwide Corporation in 2002.  David & Sandra Haas have more than 80 patents to their credit as well as many technical and scientific publications.

In 1978, David was the main narrator in the U.S. Bureau of Radiological Health Film on 'Analytical X-Ray Safety' which is used to this day.  Dr. Haas has recently published a book by ASIS International entitled:  “Personal Identification – Its Modern Development and Security Implications".  It reviews the history and reasons for modern personal identification documents such as Passports, National Identity Cards, etc.  Dr. Haas has also published a monograph on the development of Electronic Security Screening for Aviation Passenger Screening between 1968-1973.

First X-ray Applications:  Freezing Protein Crystals To Prevent Radiation Damage &The Invention of the Airport Low-Dose X-ray Security Scanners

Beginning in the 1950s, protein crystallography produced the three dimensional atomic structures of the first protein molecules as well as other biological macromolecules such as DNA.  Remarkably, this led to a revolution in biology, biochemistry, and related sciences through the new field of “Structural Biology” (the molecular structures within bacteria, cells and viruses).  With training in Biophysics and X-Ray Protein Crystallography, I worked on the problem of reducing x-ray radiation damage in protein crystals beginning in 1966.  This lead to the first successful freezing of protein crystals and the publication in 1970 demonstrating that suitable freezing of protein crystals reduces the radiation damage by many fold.  Forty five years later, I became aware of the fact that this work had lead to macromolecular CryoCrystallography, with more than 100,000 three-dimensional protein structures being solved today, all available free to the world from the "Protein Data Bank".  The development of the synchrotron and remarkable software/computers contributed to this revolution.  Today, biological scientists and most new drug designs employ the surface structure of protein molecules which are determined by x-ray crystallography.  My first hand experience recounts this early history.

Shortly thereafter in 1970, I joined the X-ray group of Philips Electronic Instruments in Mahwah NJ (where I designed many of the early airport passenger x-ray security scanners).  Between 1968 & 1973, passenger aircraft hijackings became a major worldwide problem with hundreds of aircraft hijackings each year (because no passenger screening was performed).  Finally after years of disruption, a solution was found with metal detectors for people and low-dose x-ray systems for luggage.  Because of the remarkable work of two Philips engineers who invented the first low-dose x-ray system for passenger screening in Mahwah NJ, Electronic Security Screening for passenger and public security is now used everyday - worldwide.  My presentation describes the recent book on the history of Electronic Security Screening that (probably) saved the aviation passenger industry as well as the worldwide tourism industry. 

The Technology Behind Aviation Passenger Security Screening – How It Began (1968-1973); Why It Will Continue Forever; Why We Fly Safely Today

Between 1968 & 1973, commercial aircraft hijackings became a major worldwide problem as no passenger screening was performed and hundreds of aircraft were hijacked each year - eventually morphing into murder, extortion and terrorism.  I was involved in the first ten years of developing and manufacturing the low-dose airport x-ray systems.  Today, forty years later passengers still walk through metal detectors and still have their luggage inspected by x-rays, exactly as it was performed on January 5, 1973 when mandatory aviation passenger screening began.  Because of the remarkable work of two Philips engineers who invented the first low-dose x-ray system for passenger screening in Mahwah NJ, Electronic Security Screening for passenger and public security is now used everyday - worldwide.  We will discuss who invented this solution, and how they enabled the Federal Government to decide to implement mandatory passenger.  Recent work on the origin of Electronic Security Screening explains this, along with the fact that these two engineers probably saved the aviation passenger business and worldwide tourism from decades of disaster. 

The Technology of Personal Identification – Why We Had No IDs A Century Ago, Yet Today We Must Always Carry Trusted & Secure ID Documents

Before 1900, almost nobody in the world had any personal identification documents, but today they are absolutely essential for citizenship.  Under the auspices of ASIS International (formerly American Society for Industrial Security), I began research to determine who invented the photo ID (card/badge), but it became the history of IDs like passports, ID credentials, photo driver’s licenses, birth certificates, etc.  In most developed countries other than the United States and the United Kingdom, Personal ID Numbers are issued to every citizen (though not always ID cards).  We will discuss why the United States has the poorest Personal Identification System in the world as demonstrated by the 2014 statistics of $16 billion stolen from 12.7 million U.S. citizens.
