Question: Who did V. D. Krishnaswami work with that died in 1976?

<P0-S0> Rouben V. Ambartzumian (Armenian: Ռուբեն Վ․ Համբարձումյան ;Russian: Рубен В. <P0-S1>  Амбарцумян ) (born 1941) is an Armenian mathematician and Academician of National Academy of Sciences of Republic of Armenia . <P0-S2>  He works in Stochastic Geometry and Integral Geometry where he created a new branch, combinatorial integral geometry. <P0-S3>  The subject of combinatorial integral geometry received support from mathematicians K. Krickeberg and D. G. Kendall at the 1976 Sevan Symposium (Armenia) which was sponsored by Royal Society of London and The London Mathematical Society. <P0-S4>  In the framework of the later theory he solved a number of classical problems in particular the solution to the Buffon Sylvester problem as well as the Hilbert's fourth problem in 1976. <P0-S5>  He is a holder of the Rollo Davidson Prize of Cambridge University of 1982. <P0-S6>  Rouben's interest in Integral Geometry was inherited from his father. <P0-S7>  Nobel prize winner Allan McLeod Cormack Laureate for Tomography wrote: "Ambartsumian gave the first numerical inversion of the Radon transform and it gives the lie to the often made statement that computed tomography would have been impossible without computers". <P0-S8>  Victor Hambardzumyan, in his book "A Life in Astrophysics", wrote about the work of Rouben V. Ambartzumian, "More recently, it came to my knowledge that the invariance principle or invariant embedding was applied in a purely mathematical field of integral geometry where it gave birth to a novel, combinatorial branch." <P0-S9>  See R. V. Ambartzumian, «Combinatorial Integral Geometry», John Wiley, 1982. <SEP> <P1-S0> V. D. Krishnaswami (18 January 1905 - 15 July 1970) was an Indian archaeologist who served as Director of the Salar Jung Museum, Hyderabad, the Indian Museum and as Deputy Director-General of the Archaeological Survey of India. <P1-S1>  He is known for his pioneering work in unearthing Stone Age and megalithic sites in South India, especially those around Madras city in the 1940s and 1950s along with Mortimer Wheeler. <SEP> <P2-S0> Sir Robert Eric Mortimer Wheeler (10 September 1890 – 22 July 1976) was a British archaeologist and officer in the British Army. <P2-S1>  Over the course of his career, he served as Director of both the National Museum of Wales and London Museum, Director-General of the Archaeological Survey of India, and the founder and Honorary Director of the Institute of Archaeology in London, further writing twenty-four books on archaeological subjects. <SEP> <P3-S0> Kodayanallur Vadamamalachery Soundararajan (born 17 February 1925) is an Indian archaeologist who served as Superintendent of the Chennai circle and later, a Joint Director General of the Archaeological Survey of India. <P3-S1>  He was known for his pioneering work in excavating Stone Age and megalithic sites of South India along with Mortimer Wheeler and V. D. Krishnaswami in the late 1940s and the 1950s. <P3-S2>  Some of the sites excavated by Soundararajan include Sanur (near Chengalpattu) (1950), Kundrathur (1955–56), Perur (1970–71), Malayamputtu (1970–71) and Poompuhar (1970–71, 1973–74).
