Tucson, Arizona

===Nicknames===
Tucson is commonly known as "The Old Pueblo". While the exact origin of this nickname is uncertain, it is commonly traced back to Mayor [[Robert N. Leatherwood|R. N. "Bob" Leatherwood]]. When [[railroad|rail service]] was established to the city on March 20, 1880, Leatherwood celebrated the fact by sending telegrams to various leaders, including the [[President of the United States]] and the [[Pope]], announcing the "ancient and honorable pueblo" of Tucson was now connected by rail to the outside world. The term became popular with newspaper writers who often abbreviated it as "A. and H. Pueblo". This in turn transformed into the current form of "The Old Pueblo".<ref>{{cite news|url=http://tucson.com/news/state-and-regional/history-and-culture/life-in-the-old-pueblo-here-s-how-tucson-came/article_8bf4391f-1499-5e71-bdd8-178e3c52b96d.html|title=Life in the Old Pueblo: Here's how Tucson came to own its charming nickname|author=Jim Turner|newspaper=Arizona Daily Star|access-date=July 7, 2018|archive-url=https://web.archive.org/web/20180707201830/https://tucson.com/news/state-and-regional/history-and-culture/life-in-the-old-pueblo-here-s-how-tucson-came/article_8bf4391f-1499-5e71-bdd8-178e3c52b96d.html|archive-date=July 7, 2018|url-status=live}}</ref>

In the early 1980s, city leaders ran a contest searching for a new nickname. The winning entry was the "Sunshine Factory".<ref>{{cite news|url=https://news.google.com/newspapers?id=GY5PAAAAIBAJ&pg=5518,5331610&dq=tucson+sunshine+factory&hl=en|title='The Sunshine Factory' Picked as New Nickname for Tucson|date=November 15, 1981|work=Ocala Star-Banner|page=11A|location=Ocala, Florida|agency=Associated Press|access-date=November 12, 2015|archive-url=https://web.archive.org/web/20150908094015/https://news.google.com/newspapers?id=GY5PAAAAIBAJ&sjid=aQYEAAAAIBAJ&pg=5518,5331610&dq=tucson+sunshine+factory&hl=en|archive-date=September 8, 2015|url-status=live}}</ref>  The new nickname never gained popular acceptance, allowing the old name to remain in common use.<ref>{{cite news|url=https://news.google.com/newspapers?id=JGsaAAAAIBAJ&pg=6594,4066995&dq=tucson+sunshine+factory&hl=en|title=There's more to Tucson than Sun, Guns, Scenery|last=Abel|first=Barbara|date=January 8, 1984|work=The Milwaukee Journal|pages=Travel 1–4|access-date=November 12, 2015|archive-url=https://web.archive.org/web/20150908091903/https://news.google.com/newspapers?id=JGsaAAAAIBAJ&sjid=NCoEAAAAIBAJ&pg=6594,4066995&dq=tucson+sunshine+factory&hl=en|archive-date=September 8, 2015|url-status=live}}</ref>  Tucson was dubbed "[[Optics Valley]]" in 1992 when ''[[Business Week]]'' ran a cover story on the Arizona Optics Industry Association.<ref>{{cite book|last=Liou|first=Koutsai T. |title=Handbook of economic development|url=https://books.google.com/books?id=cxxJkKYAzioC&q=tucson+optics+valley&pg=PA205|year=1998|publisher=CRC Press|isbn=0-8247-0181-X|page=205}}</ref>
