In 1942, University of California, Davis (UCD) biologist, Jack Hanna recognized the need for breeding tomato varieties that ripen uniformly and withstand the rigors of mechanical harvesting. In 1949, UCD agricultural engineer Coby Lorenzen and Hanna began developing a mechanical tomato harvester. Parallel efforts by others, notably those started in 1957 by agricultural engineer Bill Stout and horticulturist Stan Ries of Michigan State University, eventually resulted in several different harvesting mechanisms. In the late 1950s, UCD agricultural engineer Steven J.

Skid Steer Loader
Society: ASABE Main Category: Agricultural & Biological Sub Category: Mechanization Era: 1950-1959 DateCreated: 1957 Bonanzaville Historic Museum West Fargo State: ND Zip: 58078 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/skid-steer-loader-43.aspx Creator: Keller, Cyril and Louis

Brothers Cyril and Louis Keller designed and built the first small, lightweight, three-wheel, front-end loader in their machinist-blacksmith shop in Rothsay, Minnesota. A local farmer wanted to mechanize cleaning manure from his obstacle-filled, two-story turkey barn. The machine, first used in 1957, was able to turn completely around within its own length. Melroe Manufacturing Company, Gwinner, ND purchased the rights to the Keller loader and hired the Kellers to continue development of the loader in 1958.

On April 12, 1955, Dr. Jonas Salk, a slightly built, forty-year-old research professor from the University of Pittsburgh, became a hero. On that morning, before one hundred and fifty news reporters and five hundred scientists and physicians crammed into an auditorium at the University of Michigan, “amid fanfare and drama far more typical of a Hollywood premiere than a medical meeting,” according to an account in The New York Times, it was announced that Dr. Salk had developed a vaccine that had been found effective in preventing poliomyelitis.

During the winter of 1957-58, Earl E. Bakken developed the first wearable transistorized pacemaker, the request of heart surgeon, Dr. C. Walton Lillehei. As earlier pacemakers were AC-powered, this battery-powered device liberated patients from their power-cord tethers. The wearable pacemaker was a significant step in the evolution to fully-implantable units.

Larsson (26th May 1915 to 28th December 2001) was the first recipient of an implantable pacemaker. He received the first device in 1958 and had a total of 26 devices during his life. He became an advocate for patients needing pacemakers, campaigning for greater funding and research in this area. Era_date_from: 1957
First Television Broadcast in Western Canada

On 16 December 1953, the first television broadcast in Western Canada was transmitted from this site by the Canadian Broadcasting Corporation's CBUT Channel 2. The engineering experience gained here was instrumental in the subsequent establishment of the more than one thousand public and private television broadcasting sites that serve Western Canada today.

First Semiconductor Integrated Circuit (IC)

On 12 September 1958, Jack S. Kilby demonstrated the first working integrated circuit to managers at Texas Instruments. This was the first time electronic components were integrated onto a single substrate. This seminal device consisted of a phase shift oscillator circuit on a tiny bar of germanium measuring 7/16” by 1/16” (11.1 mm by 1.6 mm). Today, integrated circuits are the fundamental building blocks of virtually all electronic equipment.

At this facility on 20 December 1951 electricity was first generated from the heat produced by a sustained nuclear reaction providing steam to a turbine generator. This event inaugurated the nuclear power industry in the United States. On 4 June 1953 EBR-I provided the first proof of "breeding" capability, producing one atom of nuclear fuel for each atom burned, and later produced electricity using a plutonium core reactor.

The demonstrated success in space flight is the result of electronic technology developed at Cape Canaveral, the J. F. Kennedy Space Center, and other sites. A wide variety of advances in radar tracking, data telemetry, instrumentation, space-to-ground communications, on-board guidance, and real-time computation were employed to support the U.S. space program. These and other electronic developments provided infrastructure necessary for the successful landing of men on the moon in July 1969 and their safe return to earth.

In 1954 three researchers at Bell Laboratories published the results of their discovery of the world’s first practical ‘photovoltaic’ (henceforth abbreviated by ‘PV’) cell which was capable of converting sunlight into electricity, first at 4% and later at 6% conversion-efficiency[1]. In 1959 Sharp Corporation began R&D of silicon monocrystal PV-cells, with mass production starting in 1963[2], and commercialized a variety of mono/multi-crystalline PV-cells for everything from satellites to lighthouses, and industrial applications to residential use[2].
