The elder Buehman had immigrated to the United States in 1868, traveling throughout the nation and Mexico, before settling down in Tucson in 1874.

[4] He attended Tucson Public Schools, as well as the University of Arizona's preparatory academy, before going to the Michigan College of Mining and Technology, where he obtained both B. S. and E. M. degrees in 1911.

[16][17] In 1918 Buehman chose not to run for re-election, instead throwing his name in the ring for the Republican nomination for one of the two Senate seats from Pima County.

[28] He won the Republican primary in February, but narrowly lost, by just over 300 votes, to Democrat Don Hummel in the general election in April 1955.

[29][30] In 1925 Buehman collaborated with Lone Wolf on the artist's portrait of Leighton Kramer, a Tucsonan rodeo sponsor.

[32] In 1934, Buehman's photographs of the kidnapping scene of June Robles gained national attention.

[33][34] In August 1939, Buehman was chosen to be the president of the Photographer's Association of America, serving in that capacity through 1940.

[2][35] Buehman was also an associate in the Royal Photographic Society of Great Britain, being admitted in February 1941.

[2][36] In August 1949, Buehman was elected president of the American Society of Photographers (ASP), after having served the prior two years as its vice-president.

[40] In December 1949, Buehman accepted the position of executive manager of the Photographers' Association of America (PAA), which entailed him moving to Cleveland, Ohio.

[44] His social activities included heavy participation in the Kiwanis Club,[45] the Y. M. C. A.,[46] and the Tucson Merchant's Association.

[4] In 1968, shortly after Buehman's death, a collection of over 140,000 photographs taken by him and his father was donated to the Arizona Pioneers Historical Society.
