American professor Stephen G. Miller, noted for his unflagging work over more than three decades to unlock the story of the archaeological site of Ancient Nemea in the northeast Peloponnese, has died at 79. No cause was given.

Culture Minister Lina Mendon said that, “With the loss of Stephen Miller, archaeological research has lost a great, dedicated scientist, while Greece has lost a great friend,” Mendoni said in a message, while praising the late archaeologist’s “scientific brilliance, humanity and progressive thinking,” reported Kathimerini.

 US Ambassador Geoffrey R. Pyatt tweeted: “Very sad news about an American scholar who contributed greatly to the cultural ties between our countries (and California),” noting Miller was  Professor of Archaeology at the University of California at Berkeley between 1973 and 2004.

Born in Goshen, Indiana, in 1942, Miller became, while serving as Director of the American School of Classical Studies at Athens from 1982 until 1987, the report said.

In 1971, Miller was appointed Director of Excavations at Nemea and began work at the site two years later. His team uncovered the Sanctuary of Zeus and the ancient stadium, constructed around 330 BC.

In 1994, Miller founded The Society for the Revival of the Nemean Games. The first contemporary games were held two years later.

He was bestowed the Greek title of Grand Commander of the Order of Honor in 2005, while Greece’s President at the time signed an honorary naturalization order, adding to his recognition by Greece for his work.
