History<\/h3>\t\t\t

In 1935, a Milwaukee diver, Max Gene Nohl, had received national publicity as the result of his salvage operations on a sunken steamship, the “John Dwight.” This brought him to the attention of a Hollywood producer, Col. John D. Craig, who was interested in the possible salvage of the torpedoed Cunard liner, the “Lusitania,” which lay in 312 feet of water off the Irish Coast. At that time, no equipment or reliable techniques were available for diving operations at such a depth, and it was obvious that such a project would require both physiological experimentation and an advance in diving equipment design. Nohl had already been working on diving equipment to work at the Lusitania\u2019s depth.\u00a0 Additional support equipment would need to be designed and built for the project. Nohl using the suit design from his thesis as a starting point began experimentation on building the necessary gear. Jack Browne worked with Nohl and Craig to get the equipment ready. Browne and Nohl worked together on the design of a new type of lightweight, self-contained diving suit. In April 1937 Max Nohl contacted Dr. End about his development of Helium\/ Oxygen decompression tables. Dr. End suggested using the recompression chamber in the basement of the Milwaukee County Hospital to test their theories. They worked with Dr. End to explore the promising possibility of preventing nitrogen narcosis and Caisson Disease (the Bends) by having the diver breathe a mixture of helium and oxygen rather than air.<\/p>\n

The first result of this collaboration was the forming of Diving Equipment & Salvage Company (DESCO) as the manufacturer of the newly designed diving equipment. Mr. Norman Kuehn, a Milwaukee businessman, largely financed the new corporation. Browne and Nohl became its first full-time employees. Browne was also one of its shareholders. The company was set up in the rear of Kuehn Rubber Company on North 4th Street in Milwaukee. Norman Kuehn was made Vice-President of the firm.<\/p>\n

The second result was that, On December 1, 1937 in the cold waters of Lake Michigan, Max Nohl succeeded in diving to a depth of 420 feet, breaking a depth record which had been held by a U.S. Navy diver Frank Crilley, since 1915. Nohl accomplished this feat using DESCO’s new diving equipment and breathing a heliox mixture prescribed by Dr. End. As war neared in Europe the British Admiralty began placing more and more restrictions on John Craig\u2019s expedition so it was finally called off in 1938. Max Nohl not seeing a bright future for the fledgling company went on to other projects.<\/p>\n

Jack Browne kept DESCO going by designing and selling lightweight self contained suits. Through 1938 to December of 1941 the small firm plodded along. Jack experimented with new designs for breathing tanks and lighter suits.<\/p>\n

With the outbreak of World War Two Mr. Kuehn urged Jack to go to Washington. \u201cTell the Navy what you know about diving suits. Show the boys what you have done and can do.\u201d Jack did. In January of 1942 he headed east and returned with a $5000 order for three self-contained suits. That first order led to others until DESCO was producing more diving equipment than anyone else in the world.<\/p>\n

World War II shifted the focus of the company to standard diving equipment production. The war effort brought large Navy contracts for diving equipment to DESCO.\u00a0 The company quickly became the largest diving equipment manufacturer in the world.\u00a0 DESCO made over 3000 Mark V and Navy Helium Helmets during this period. The company\u2019s research and development roots were not overlooked by the government. DESCO was contracted by the Office of Strategic Services (forerunner of the CIA) to design and build a compact oxygen rebreather. The result was the DESCO B-Lung. This unit, for the first time, permitted divers to swim freely under the surface, in the manner of SCUBA divers today, but without producing bubbles, which might disclose their position. Other projects included the Browne U.S. Navy Diving Mask, The Browne Lightweight Suit (Bunny Suit), and the Buie Mixed Gas Helmet. The government contracts included not only conventional hard-hat gear, but also weightbelts, shoes, knives, tools, recompression chambers, and miscellaneous items. By V-J Day, DESCO was producing more diving equipment than any other company in the world.<\/p>\n

By 1945 DESCO had its own pressurized wet tank for research and development. On April 27, 1945, Jack Browne used this tank to “dive” to still a new record depth of 550 feet of seawater. Mr. Browne used a U.S. Navy Lightweight Diving Suit (bunny suit) for the tank dive.\u00a0 As in the case of Nohl’s earlier dive, he breathed a heliox mixture under the supervision of Dr. End. Both dives were milestones in the development of modern techniques of mixed-gas diving. During this time Max Nohl left DESCO to pursue other interests. He would return briefly in the early 1950\u2019s.<\/p>\n

In 1945 the company’s name changed to Diving Equipment & Supply Co. The end of the war brought a slowdown in the diving market. Foreseeing this situation the company had begun moving into the recreational market. Products included surf boards, water skis, masks, fins, the DESCO Airmaster SCUBA regulator, and recreational rebreathers.<\/p>\n

In 1947 Jack Browne and Norman Kuehn sold the company to Alfred Dorst, E. M. Johnson, Paul Hoffman, and Irwin Knoebel. Johnson was general manager of DESCO during the war. Max Nohl at the time was looking to calm down his life a bit and he accepted an offer to return to DESCO as a technical advisor.<\/p>\n

After the Korean War, which again brought an increase in U.S. Navy contracts and orders, the ownership changed hands several times, and by 1960 it went out of the sporting goods business. Ever since, it has concentrated solely, as it did at the start, on the design and manufacture of commercial and U.S. Navy diving equipment.<\/p>\n

In May 1966, DESCO was purchased by Thomas and Marilyn Fifield. Mr. Fifield was an attorney and Mrs. Fifield served on several boards in Milwaukee. In 1968 DESCO moved to its present address at 240 North Milwaukee Street in Milwaukee. Mr. Fifield was responsible in the 1960’s for the design and development of the DESCO Diving Hat, which remains a standard piece of modern equipment for diving with air in relatively shallow water where mixed gases are not needed. Also the company has continued to improve and manufacture its famous DESCO Full-Face Mask, which originated in the early design efforts of Jack Browne and Max Nohl. This mask has probably been used in more total hours of commercial diving than any other piece of equipment ever made.<\/p>\n

The company ownership changed again in 1997 with the purchase of DESCO from Mr. Fifield by Richard Koellner. Under Mr. Koellner the company has expanded its representation of other firm\u2019s products that complement DESCO\u2019s product line.<\/p>\n<\/div>\n\t\t<\/div><\/div><\/div>
