Track Electrolab’s history and success over the following decades.

Electrolab, Inc. Established


Karl Senghaas, Founder of Electrolab


Electrolab was founded in 1976 in San Antonio, Texas, by Karl Senghaas, a German-born electrical engineer and NASA scientist.

Mr. Senghaas (1922 – 2012) was a long-standing contributor to the engineering and technology industry in San Antonio and held numerous patents for his designs. Mr. Senghaas’ design contributions included engineering patents that involved UTSA, an institution near and dear to his heart. Mr. Senghaas led the design and implementation of the first solid state interconnection of 500 dental offices at University of Texas Health Science Center (UTHSC) in the seventies. Later, Mr. Senghaas played a key role as lead in electronics design, working together with UTHSC’s design team, to patent the first “Tomerex” X-Ray machine used for full-mouth X-Ray scans.

Mr. Senghaas’ engineering contributions spanned many industries, including beverage and food service, aviation, oil & gas, and water management. Mr. Senghaas also worked with NASA teams on the development of the Photomultiplier used in space-exploration. With companies calling on Electrolab to design electronics technologies that others would not attempt, Karl Senghaas was often lovingly named “The Einstein of San Antonio”. International firms recognized his unique approach to electronics design and his unrelenting desire to find creative solutions to problems that initially appeared unsolvable. Throughout his career, Mr. Senghaas never forgot to train young engineers, providing countless opportunities for growth and achievement right here in San Antonio.

In 2013, Electrolab established the the Karl Senghaas Engineering Scholarship at UTSA, which is awarded each year to a student of Electrical Engineering.
