In 1997 Lucent Technologies created this replica to commemorate the 50th anniversary of the invention of the point-contact transistor at Bell Labs in December 1947.

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.

Arne H. W. 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.

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.
