the importance of finding a letter from Darwin that had been stolen 30-years prior by an intern at the Smithsonian. Berra explained that Darwin was trained as a geologist and would have been "interested in what was going on in America" this letter would be one of only 7,000 letters written by Darwin and anything by Darwin "is of historical significance and scientific significance". Berra has pushed for the city of Darwin to fully embrace the man and legacy that they are named for. In 2014 Berra said that when he started coming to Darwin in 2001 he was "struck by the fact that there was nothing visible about him (Darwin) to the public." Today, the Beagle ship bell chimes and bust of Charles Darwin reside in Darwin's Civic Center, and the former Northern Territory University is renamed Charles Darwin University. Berra gave the keynote address on Charles Darwin in 2009 at the 200th anniversary of the birth of Charles Darwin held at the Darwin Convention Center in Darwin. After retirement In 1995, Berra retired from teaching full-time. In 2009 he won his third Fulbright Fellowship, and continued to publish books and scientific papers. In 2016 as a Professorial Fellow stationed at Charles Darwin University in Darwin Australia, Berra continued his work on nurseryfish. His research on the nurseryfish was to investigate the male's unique adaptation, carrying thousands of fertilized eggs on a hook "like a bunch of grapes". Berra wanted to know how the embryos attached to the hook, and if the male was the genetic father of the embryos. During one of the research trips in 2011 with Wedd on the Adelaide River they encountered a 5-metre crocodile locals call Agro eating the fish that Berra and Wedd had trapped in a net they were using in their research. Argo got his teeth into the net and before Berra and Wedd could attempt releasing it, Argo tore a 'humungous hole' in the net. The rest of the day Argo followed them around the river. In 2009 the Smithsonian Institution received Berra's collection of 260 species of rare fishes. Berra and his wife Rita M. Berra endowed the first chair established at Ohio State's regional campus. Berra hopes that the chair will be filled by a scientist that will do field work and return to teach at the Mansfield campus, also Berra made the bequest to honor his wife
