ജർമനിയിൽ ജനിച്ച ഒരു അമേരിക്കൻ ഗണിതശാസ്ത്രജ്ഞനും ഇലക്ട്രിക്കൽ എഞ്ചിനീയറും യൂണിയൻ കോളേജിലെ പ്രൊഫസറുമായിരുന്നു Charles Proteus Steinmetz (born Karl August Rudolph Steinmetz, ഏപ്രിൽ 9, 1865 – ഒക്ടോബർ 26, 1923). എഞ്ചിനീയർമാർക്ക് ഗണിതസിദ്ധാന്തങ്ങൾ നിർമ്മിക്കുകവഴി അമേരിക്കയിലെ വിദ്യുത്‌ച്ഛക്തി വ്യവസായത്തിന്റെ വികസനത്തിനു കാരണമായ ഏ സി വൈദ്യുതിയുടെ സിദ്ധാന്തങ്ങൾ രൂപീകരിക്കുന്നതിൽ മുൻപന്തിയിൽ ഉള്ളയാളായിരുന്നു ഇദ്ദേഹം. hysteresis -ൽ ഉള്ള ഇദ്ദേഹത്തിന്റെ കണ്ടുപിടിത്തങ്ങൾ നൂതനവും കാര്യക്ഷമതയേറിയതുമായ വൈദ്യുതയന്ത്രങ്ങൾ വ്യവസായത്തിൽ ആവിഷ്കരിക്കുന്നതിന് നിദാനമായി.[1][2][lower-alpha 1]


Steinmetz maintained a small cabin overlooking the Mohawk River near Schenectady, New York.

താഴെപറയുന്ന മേഖലകളിൽ അദ്ദേഹം ജോലിചെയ്തിരുന്നു:

He was granted an honorary degree from Harvard University in 1901[3] and a doctorate from Union College in 1903.[3]

Steinmetz wrote 13 books and 60 articles, not all about engineering.[further explanation needed] He was a member and adviser to the fraternity Phi Gamma Delta at Union College, whose chapter house there was one of the first electrified houses ever.[അവലംബം ആവശ്യമാണ്]

While serving as president of the Schenectady Board of Education, Steinmetz introduced reforms including extended school hours, school meals, school nurses, special classes for the children of immigrants, and the distribution of free textbooks.[5]


Although Steinmetz loved children and family life, he knew that both his father and grandfather suffered from the same spine deformity that afflicted him. Therefore, he did not marry, for fear of passing on his deformity to any descendants.[5]


Marconi Wireless Station in Somerset, New Jersey in 1921, on the day Albert Einstein was given a tour. Steinmetz is at center; he died two years later.

Steinmetz died on October 26, 1923 and was buried in Vale Cemetery, Schenectady, New York.[6]

Based on Steinmetz experiments, "Steinmetz's formula" defines the approximate heat energy due to magnetic hysteresis released, per cycle per unit area of magnetic material.[lower-alpha 2][7] Steinmetz equivalent circuit theory is still widely used for the design and testing of induction motors.[8][9]

One of the highest technical awards given by the Institute of Electrical and Electronics Engineers, for major contributions to standardization within the field of electrical and electronics engineering, is named in his honor as the IEEE Charles Proteus Steinmetz Award. Other awards include the Certificate of Merit of Franklin Institute, 1908; the Elliott Cresson Medal, 1913; and the Cedergren Medal, 1914.

His connection to Union College is celebrated with the annual Steinmetz Symposium,[10] a day-long event in which Union undergraduates give presentations on research they have done. Steinmetz Hall, which houses the Union College computer center, is named after him.

Steinmetz was portrayed in 1959 by the actor Rod Steiger in the CBS television anthology series, The Joseph Cotten Show. The episode focused on his socialist activities in Germany.

A Chicago public high school, Steinmetz College Prep, is named for him.

A public park in north Schenectady, New York was named for him in 1931.[11]

In popular culture[തിരുത്തുക]

Steinmetz is featured in John Dos Passos's U.S.A. trilogy in one of the biographies.[12] He also serves as a major character in Starling Lawrence's The Lightning Keeper.[13]

Novelist John Ball grew up in Steinmetz's house. His parents were graduate students paid by General Electric to live with and take care of the man Ball called "Uncle Steinie". Ball used to tell his Steinmetz stories at the Southern California Mystery Writers Association meetings.[അവലംബം ആവശ്യമാണ്]

Steinmetz is a major character in the novel Electric City by Elizabeth Rosner. In this epic story of technology, Rosner connects Steinmetz's early ethos as a socialist with his humanitarian vision of a better society based on technological progress: "The political arena that had summoned him in his youth, Socialist views that sent him into exile all those years earlier, further contributed to a seemingly endless hunger for change".[14]
