Karl Connell

  As a talented physician and surgeon, Karl Connell took a special interest in studying various gases and their chemical compositions. A graduate of Omaha (Central) High School and Creighton Medical College, Connell’s study led to two key medical science contributions.
  Connell particularly sought to improve the use of anesthetics during surgery. Through his research, he invented the “Connell Ether Vaporizer.” It significantly reduced the dangers of undergoing anesthesia by allowing doctors to administer consistent and controlled dosages throughout any length of time. Due to its effectiveness, the vaporizer was eventually utilized in many prominent hospitals across the United States.
  In 1917, when the United States entered into WWI, Connell joined the American Expeditionary Forces as a major in the division of chemical warfare. Due to his specialized knowledge of gases, Connell was commissioned by General John J. Pershing to create an effective shield against deadly gases being used by German soldiers. He experimented with various concentrations of gases and tested the efficiency of several models of gas masks. Not satisfied with the inadequate performance of the traditional gas mask, Connell constructed a new type of gas mask. He created a mask that completely protected soldiers from all gases used during WWI.
  The improved gas mask was known as the “Connell” or “Victory” mask. The “Connell” mask became the standard gas mask issued by the United States war department. In 1923, Connell was awarded the Distinguished Service Medal by the United States Department of War for developing a superior gas mask that unquestionably saved lives.
