Introduction

Calyampudi Radhakrishna Rao, (10 September 1920 – 22 August 2023), commonly known as C. R. Rao, was an Indian-American mathematician and statistician.
In 2023, Rao was awarded the International Prize in Statistics, an award often touted as the “statistics’ equivalent of the Nobel Prize“.

Early Life and Education

Born on September 10, 1920, in Huvvina Hadagalli, Karnataka, had humble beginnings.
His parents, C. Doraswamy Naidu and A. Laxmikanthamma, were pivotal in nurturing his intellectual growth from a young age.
Rao displayed exceptional mathematical talent early on, memorizing multiplication tables at the age of five.

Academic Journey

Rao pursued his education in mathematics, obtaining a BA (Hons) degree and an MSc in mathematics from Andhra University.
His journey led him to the Indian Statistical Institute (ISI) in Kolkata, where he began to explore the field of statistics, initially as a means to secure future employment.
At ISI, Rao’s career took off as he engaged in research, published papers, and earned an MA in 1943 with record-breaking marks.
In 1945, Rao authored a seminal paper in the Bulletin of the Calcutta Mathematical Society, detailing his groundbreaking contributions, including the Cramér-Rao lower bound, the Rao-Blackwell Theorem, and insights into ‘information geometry’.
These results revolutionized statistical inference and data analysis.

Contributions to Statistics

Cramér-Rao Lower Bound: provided a framework to assess the accuracy of statistical estimates.
Rao-Blackwell Theorem: offered a means to optimize estimates, significantly improving the quality of statistical inferences.
Wide-ranging Impact: These contributions found applications in diverse fields such as signal processing, spectroscopy, radar systems, risk analysis, and quantum physics.

Institution Building and Leadership

Rao spent time at Cambridge University’s Department of Anthropology, analyzing human skeletal measurements and earning his PhD.
He returned to ISI and held various leadership positions, contributing to the institution’s growth and influence.
Rao established research units in fields like economics, sociology, psychology, genetics, anthropology, and geology, promoting interdisciplinary research.
He introduced courses and degree programs, including BStat, MStat, and a PhD program in theoretical statistics and probability.

Impact on National Statistical System

Collaboration with P.C. Mahalanobis: Rao worked closely with P.C. Mahalanobis to establish the State Statistical Bureaus, contributing to the development of India’s robust statistical system.
Government Committees: Rao’s involvement in government committees further enhanced statistical education, research, and national statistical systems in India.

Transition to the United States

Rao’s retirement at age 60 led him to the United States, where he held professorial positions at the University of Pittsburgh, Pennsylvania State University, and the University at Buffalo.
His time in the US resulted in 274 research papers, surpassing his Indian output of 201, highlighting his passion for research.

Indian Statistical Institute

Founded by Professor P.C. Mahalanobis in Kolkata on 17th December 1931.
Gained the status of an Institution of National Importance by an act of the Indian Parliament in 1959.
Headquarters in the northern fringe of Kolkata with centers in Delhi, Bangalore, Chennai, and Tezpur.
Focus on research in Statistics and related disciplines.
Offices in various Indian cities engaged in projects and consultancy in Statistical Quality Control and Operations Research.
Dedicated to research, teaching, and application of statistics, natural sciences, and social sciences.

International Prize in Statistics:

Awarded every two years by a collaboration of five major international statistics organizations.
Recognizes exceptional achievements in the field of statistics, particularly for practical applications and cross-disciplinary breakthroughs.
Modeled after renowned awards like the Nobel Prize, Abel Prize, Fields Medal, and Turing Award.
