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 Semiconductor Integrated Circuit (IC)
Society: IEEE Main Category: Electric Sub Category: Era: 1950-1959 DateCreated: 1958 Texas Instruments, North Campus Dallas State: TX Zip: 75243 Country: USA Website: http://www.ieeeghn.org/wiki/index.php/Milestones:First_Semiconductor_Integrated_Circuit_%28IC%29,_1958 Creator: Kilby, Jack S.

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.
