The four-vertex theorem stands as a fundamental contribution to plane geometry, emerging from the work of Syamadas Mukhopadhyaya during the early twentieth century. His research into the properties of plane arcs established lasting geometric principles, ensuring his technical legacy remains embedded in modern mathematical literature through the theorem that bears his name and his specific geometric insights.
Early Education and Career
Born in 1866 in Haripal, Hooghly district, Bengal Presidency, British India, Mukhopadhyaya pursued a comprehensive education. He graduated from Hooghly College before obtaining his M.A. degree from Presidency College in Calcutta. Further academic training included classes at the Indian Association for the Cultivation of Science. In 1910, he completed his Ph.D. at the University of Calcutta, where he was eventually appointed professor of mathematics at the Rajabazar Science College by Asutosh Mookerjee.

Mukhopadhyaya focused his primary efforts on differential geometry, with his research noted by international contemporaries. Jacques Hadamard maintained professional correspondence with him regarding the geometry of plane arcs, and Wilhelm Blaschke cited his work in his own publications. Beyond his specialized research, Mukhopadhyaya held faculty positions at Bangabasi College and Bethune College, where he provided instruction in mathematics, English literature, and philosophy.
Professional Leadership and Final Years
In 1932, he became the president of the Calcutta Mathematical Society, a position he retained until his death. His academic tenure included a 1933 visit to Europe under a Ghose Travelling Fellowship, intended for the study of pedagogical methods, during which he lectured at Paris University. He died in 1937 in Kolkata due to heart failure.
