Shikaripura Ranganatha Rao () (1 July 1922 – 3 January 2013), commonly known as Dr. S. R. Rao, was an Indian archaeologist who led teams credited with discoveries of a number of Harappan sites including the port city Lothal and Bet Dwarka in Gujarat. Biography and career Rao was born on 1 July 1922 into a Madhwa Brahmin family. He completed his education from Mysore University. He worked in the Archaeological Department of Baroda State and subsequently served the Archaeological Survey of India in various capacities. Rao has led excavations of many important sites such as Rangpur, Amreli, Bhagatrav, Dwarka, Hanur, Aihole, Kaveripattinam and others. One of his most important works were leading the research and excavations at Lothal, the earliest known port in history and the most important Indus-era site in India. Rao was the recipient of Jawaharlal Nehru Fellowship and a doctorate of literature from Mysore University. Rao had supervised excavation of several historic sites across the country in the West and South. He was also associated with conservation of monuments such as Taj Mahal and forts. Despite officially retiring in 1980 Rao was requested to work for the ASI Director General in leading Indian archaeological projects. It was under Rao's initiative that the NIO opened a marine archaeology research centre in 1981, under the stewardship of then director Syed Zahoor Qasim, which grew into a world recognised body. He was the founder of the Society of Marine Archaeology in India. Rao has been at the forefront of Indian archaeology for many decades - he was involved in extensive research into India's ancient past, from the sites of the Indus Valley civilization to excavations pertaining to the Kurukshetra War. Indus script decipherment claim Rao (1992) claimed to have deciphered the Indus script. Postulating uniformity of the script over the full extent of Indus-era civilization, he compared it to the Phoenician Alphabet, and assigned sound values based on this comparison. His decipherment results in an "Sanskritic" reading, including the numerals aeka, tra, chatus, panta, happta/sapta, dasa, dvadasa, sata (1, 3, 4, 5, 7, 10, 12, 100). While mainstream scholarship is generally in agreement with Rao's approach of comparison, the details of his decipherment have not been accepted, and the script is still generally considered undeciphered. John E. Mitchiner, after dismissing some more fanciful attempts at decipherment, mentions that "a more soundly-based but still greatly subjective and unconvincing attempt to
