Alvin Cohan is responsible for a body of work, which started with the first machine in his basement and culminated in a $10 million company employing 50 people. His work encompasses the advancement of production printing equipment for the container industry.

A glance at the average American household shows at least 10 different containers in the refrigerator (soda and beer cans, yogurt, cottage cheese, ice cream, sour cream and salad dressing containers) and another 10 in the bathroom (toothpaste tubes and pumps, shampoo jars and bottles, moisturizers, creams, band aids, pharmaceutical products, etc.) that have been decorated by systems Cohan either directly manufactured or by systems using his inventions. He developed the ultraviolet (UV) curing system to the high standards the printing industry enjoys today. 

Production speeds, print quality and material handling considerations were advanced by Alvin Cohan. His patents currently in use include oval cosmetic containers decorated by silk screen; and the printing on Band Aid and Curad bandage containers, and can lines in Canada, the United States, Germany and Venezuela. Cohan is a 1941 graduate of New Jersey Institute of Technology's Newark College of Engineering.

George deStevens, CIBA Pharmaceutical Company, Summit

In 1958, Dr. George deStevens discovered hydrochlorothiazide, a potent, non-mercurial, orally-active diuretic. In an extensive three-year program, he led a research group which synthesized over 400 derivatives. Used alone and in combination, Hydrochlorothiazide became the most widely prescribed drug for the treatment of hypertension throughout the world. Because of its potency and built-in ceiling effect, it is highly effective in removing excess fluids from the body with minimum side effects. In addition, its fixed combination with other antihypertensive drugs has facilitated the treatment and control of high blood pressure for millions of patients. As a result, the incident of stroke, renal damage and heart attacks has been markedly reduced for millions, thus leading to a significant reduction in mortality. In the U.S., more than 50 million people suffer from hypertension. 

Dr. deStevens was executive vice president and director of research at CIBA and CIBA-Geigy from 1967 to 1979. In that capacity, he led research teams which developed Rimactane, a cure for tuberculosis; Celospor, a broad spectrum antibiotic; Slow-K, for potassium deficiencies in cardiovascular disorders; Apresazide, a new antihypertensive; Tegretol, for the treatment of epilepsy; Lioresal, an antispastic agent; Rengasil, for the treatment of arthritis; and Lopressor, a widely used antihypertensive agent. In addition, he pioneered the establishment of a new drug delivery system research group, which in collaboration with Alza, led to the development of Transderm-Nitro, for the treatment of angina. 

Currently, Dr. deStevens is research professor of chemistry at Drew University and among the founders of Drew's Charles A. Dana Research Institute for Scientists Emeriti. He earned a doctorate in organic chemistry and enzymology from Fordham University. In 1991, the American Chemical Society named deStevens as the first recipient of the E.B. Hershberg Award for important discoveries in medicinally active substances.

Joseph J. Mascuch (1896-1986), Breeze Corp., Union and Victory Engineering Corp., Springfield

Awarded 165 patents, Mascuch is best known for the development of the ignition shield which allows the clear reception and transmission of radio signals when the electrical system of an airplane or automobile engine is running. 

He also developed a flexible metal hose that allowed the use of safe fuel lines in aircraft, a device first used in Wiley Post's airplane "The Winnie May" in 1934. Mascuch also developed the anti-jackknife hitch that prevents trailers from jackknifing when braking. 

Rustproof standardized stainless steel automobile bumpers, propeller blade, marine bulkhead door, antenna structure, standardized helicopter hoists, the mechanism for carrying and releasing bombs and rockets, the instant reading thermocouple thermometer, and gear-driven clamps are also Mascuch devices. 

Mascuch organized Breeze Corporation in 1926 by consolidating a number of manufacturing businesses and founded Victory Engineering Corp. in 1942. He graduated from Newark Technical School, a predecessor to New Jersey Institute of Technology.

Glenn Leslie Dimmick, RCA, Camden

Among his 94 patents, Dimmick's most significant inventions are in the areas of sound motion picture recording, sound powered telephones, optical lens coating and dichroic reflectors for color television. 

The first attempts at "talking movies" used a phonograph record for the sound. But the synchronization with the movie film was a problem. A system was needed that could effectively and practically put the sound track on the movie film at the same time the video image was captured on film. Dimmick's initial invention related to sound motion picture recording was a very robust galvanometer specifically adapted for recording sound on film. The galvanometer used electrical current from the studio microphones to "wiggle" a small mirror that produced a modulated light beam to the edge of the film. 

Over the years, Dimmick invented numerous refinements, including noise reduction on the sound recording system that resulted in a robust, effective system. The RCA sound recording system with his galvanometer was still being used by the motion picture studios in 1963 when Dimmick retired, 32 years after his initial invention. 

He invented the sound powered telephone for U.S. Navy ships during World War II. The system, manufactured by RCA, uses the acoustic energy from the speaker's voice to generate enough electrical current to power the far end receiver without a battery.

Kenneth S. Johnson (1885-1956), Bell Telephone Laboratories, New York City

Kenneth S. Johnson was considered the world's foremost authority on wire transmission. Johnson developed the basic engineering measure known as the "Q" factor, or quality factor of a circuit, which has become an indispensable design aid in a wide variety of electrical engineering system applications. 

When he first used the symbol "Q" to represent the ratio of reactance to effective resistance in a coil or a condenser, Johnson could not have anticipated that within a span of 30 years this same symbol would be commonly used to describe an attribute of such dissimilar things as a resonant circuit, a spectral line, a mechanical vibrator, and a bouncing ball. 

Johnson had originally designated the ratio of reactance to effective resistance of a coil by the symbol "K." It was in 1920, while working on the practical application of the wave filter which G.A. Campbell had invented some years before, that he first employed the symbol "Q" for his parameter. Initially, Johnson used a capital "Q" for coils and a small "q" for the corresponding ratio in capacitors. Before long, was using it for both in his U.S. patent No. 1,628,983 (1927) where it is applied to the coils in an electrical network. 

Johnson also designed the 1937 telephone which was put in use throughout the country. The 1907 magna cum laude graduate of Harvard University held 53 U.S. patents.

Since then, developing and manufacturing laser bar code scanning equipment has become the primary business of the company. Traditionally, the company's bar code scanners have been used in high volume retail stores. Today, the company is developing products for scanning applications in new markets such as banking, health services, transportation and manufacturing. Its European headquarters is located in Munich, Germany. 

Knowles, who formerly worked for Westinghouse and Bell Telephone Labs, has over 20 patents ranging from semiconductors through lasers and bar code scanning.

John B. MacChesney, AT&T Bell Laboratories, Murray Hill

MacChesney, along with colleague Paul O'Connor, developed a simple vapor deposition process, known as Modified Chemical Vapor Deposition, to produce millions of kilometers of optical fibers, a process that is not only noteworthy but remains highly competitive. 

This process was key in transforming optical fibers from scientific curiosities into the highly reliable, low loss medium necessary for high-speed, high-bandwidth fiber optic communications systems. MacChesney's further inventions have enhanced the functionality and reduced the cost of today's fiber optic cables, which are installed worldwide. 

MacChesney, who has lived and worked in New Jersey the past 35 years, holds 65 patents in a diverse set of areas that impact all aspects of optical fibers. He has been a critical part of the optical-fiber based telecommunications revolution and has been remarkably successful at identifying interesting scientific areas and turning them into areas of tremendous commercial importance.

Liang Tai Wu, Bell Communications Research, Morristown

Liang Tai Wu invented a new asynchronous transfer mode (ATM) network which will form the basic building block for a wide variety of services soon to be offered on the information superhighway. The invention describes a data communications technique which can handle the transmission of both circuit and packet traffic. With ATM, circuits of any speed can be configured by varying the rate that fixed length packets (known as cells) are sent over a train of time frames generated at a basic backbone rate. 

What is most important about the technique is that it has been accepted as a common technology endorsed by the previously somewhat disjointed computer, data network and telecommunications industries to support multimedia communications. There are widespread plans for ATM deployment worldwide, for both local and wide area networking. The U.S. government has awarded many contracts to construct agency networks using ATM technology. The Information Highway Initiative is expected to enrich people's economic, social and political lives. 

Liang Tai Wu, who for the past decade has been a mentor for many young engineers and scientists in ATM technology development, has recently become a principal investigator contracted by the National Science Foundation to assist construction of its version of the National Information Highway.

James E. West, AT&T Bell Laboratories, Murray Hill

James West's inventions have brought together an unusually broad scope of technology areas that have enabled new inventions critical for the telecommunications industry. 

He developed the foil-electret transducer for sound recording and voice communications, which is the heart of most new telephones manufactured today. These developments sprung from his U.S. patent #3,118,022 (1964) entitled "Electroacoustic transducer." 

West's pioneering research on charge storage and transport in polymers led to the development of the electret transducer. This transducer is simple yet rugged, which has made it ideal to serve as the heart of most new telephones. 

In addition to applications of transducers in areas related to telecommunications equipment, West developed inventions for other applications, including use of electret transducers for blood pressure measurements. He also has significant inventions in the area of directional microphones among his 33 patents.
