Karl Kordesch is recognized as a pioneer of battery and fuel cell technology responsible for vastly extending the utility of non-petroleum electrical energy sources through the invention and refinement of electrochemical devices and processes. Through his invention of the alkaline primary battery cell, work with rechargeable batteries, and development of fuel cell/battery hybrid vehicle systems, Karl Kordesch contributed greatly to the reduction of energy waste and the global use of compact, portable energy sources.

Karl was born in Vienna, Austria on March 18, 1922 and Erna Bӧhm was born six months later, on September 8, 1922. After graduating from high school in 1940 Karl began studying at the University of Vienna. In 1941, Karl was conscripted into the German military where he served until the end of World War II in 1945. In 1946, he and Erna were married and he returned to his studies at the University of Vienna. Karl graduated in 1948 with his doctorate in chemistry and worked as a University Assistant at the University of Vienna. In 1953, Karl accepted a position with the U.S. Army Signal Corps through Operation Paperclip, an Office of Strategic Services program designed to supplement American scientific research with Axis personnel in exchange for U.S. citizenship and other benefits. Karl and Erna moved their family to New Jersey where he served with the Signal Corps until 1955 when he joined the Union Carbide Corporation. There, he developed the manganese dioxide-zinc primary cell which became the leading consumer battery worldwide. He also worked extensively with fuel cells, contributing new technology to the Apollo space missions and developing a hydrogen fuel cell/battery system capable of powering his personal vehicle, an Austin A40, efficiently for more than three years.

In 1977, Karl left his position at Union Carbide to return to Austria with Erna where he worked as director of the Institute for Inorganic Chemistry at the Graz University of Technology. There, he continued his research into rechargeable batteries, fuel cells, and more efficient methods for powering vehicles. In 1986, Kordesch founded Battery Technologies Inc., a company responsible for the manufacture of rechargeable batteries sold under Rayovac. Karl also formed the Kordesch & Associates, Inc. consulting firm in 1988. In 1997, Kordesch accepted a position as vice-president of Apollo Energy Systems where he oversaw fuel cell research for use in consumer vehicles. The Kordeschs moved to Eugene, Oregon they lived until Karl's death in 2011. Karl Kordesch was survived by his wife, Erna Kordesch, and his four children.

During his lifetime, Kordesch produced more than one hundred patents, hundreds of articles and papers, and numerous books. He was an active participant in the scientific community, frequently attending and presenting at meetings and symposia, collaborating with colleagues around the globe, and acting as a leader in his field through service as the Secretary General of the International Society for Electrochemisty. His achievements have been recognized through his receipt of the prestigious William Exner Medal, the Vittorio de Nora Gold Medal Award, and the Erwin Schrödinger Prize, among others.
