Goodwill Cryogenics Releases Cryo-Founders Calendar

This month, India’s Goodwill Cryogenics produced and shipped the first-ever “Cryo-Founders Calendar.” Dr. Vinod Chopra, Goodwill’s founder, designed it as a tribute to 12 legends of cryogenics. Each month features a different leader in the field of cryogenics including a short bio and list of notable achievements.

Included in this group are some familiar faces. William Gifford, founder of Cryomech (CSA CSM) and namesake of CSA’s William E. Gifford award honoring outstanding scientists actively performing research using a pulse tube of Gifford-McMahon cycle cryocooler, both inventions of Gifford, is December’s featured founder.

January’s founder is Sir James Dewar, inventor of the vacuum insulated flask, the first to liquefy oxygen and hydrogen and the namesake of dewar containers. Nobel Prize winner Kamerlingh Onnes, the discoverer of superconductivity and the first to liquefy helium, is featured for February. Samuel C. Collins, the “father of practical helium liquefiers” and namesake of the CEC Samuel C. Collins award, is showcased for March.

Russia’s Pyotr Kapitsa, who discovered superfluidity in liquid helium, turbine expansion cooling and won the Nobel Prize, is April’s founder. The first to liquefy helium in Britain and the founder of the International Cryogenic Engineering Conference, Kurt Mendelssohn, is the cryo-founder for May. Dr. Chopra and Mendelssohn also worked together on the dilution refrigerator in 1973. David Shoenberg, Fellow of the Royal Society and detector of the De Hass-Van Alphen effect, is given June.

Nicholas Kurti, the first to demonstrate microkelvin temperatures with adiabatic demagnetization using large electromagnets and, according to the calendar, unofficial holiday coffee waiter at the Clarendon lab in Oxford, is the featured founder for July. Olli Viktor Lounasmaa, founder of the Low Temperature lab at Helsinki University and first to discover superfluidity in helium-3, is the founder highlighted in August. September’s founder is John Bardeen, the only physicist to win the Nobel Prize twice: once for the discovery of the transistor and again for his theory of superconductivity, BCS-theory.

Rounding out the year are Alexeyevich Abrikosov and Brian Joseph at October and November, respectively. Abrikosov won the 2013 Nobel Prize for the discovery of the Abrikosov Vortex and type-II superconductors that are currently used for high field superconducting magnets. Joseph’s claim to fame was the discovery of the Josephson effect at the young age of 22, along with the 1973 Nobel Prize for tunneling in superconductors.
