User:CmdrDan/Clarify: Presidents of the University of California, Berkeley

Robert Gordon Sproul was "the last President (11th) of the University of California, Berkeley, serving from 1930 to 1952.[1][2][3][4][5]" [emphasis added]
 * Robert Gordon Sproul (May 22, 1891 – September 10, 1975) was the first system-wide President (1952-1958) of the University of California system, and the last President (11th) of the University of California, Berkeley, serving from 1930 to 1952.[1][2][3][4][5]

If Sproul was the 11th and last President of UC, Berkeley, how is it that Clark Kerr was the twelfth president of the University of California?

Clark Kerr (May 17, 1911 – December 1, 2003) was an American professor of economics and academic administrator. He was the first chancellor of the University of California, Berkeley, and twelfth president of the University of California.

Moreover, Kerr's infobox displays: "12th President of the University of California In office 1958–1967 Preceded by	Robert Gordon Sproul" How is this possible if Sproul was the last President (11th) of the University of California, Berkeley?

 * In March 1951, the University of California began to reorganize itself into something distinct from its campus in Berkeley, with UC President Robert Gordon Sproul staying in place as chief executive of the UC system, while Clark Kerr became the first chancellor of UC Berkeley[9][10][11][12] and Raymond B. Allen became the first chancellor of UCLA.[13] However, the 1951 reorganization was stalled by resistance from Sproul and his allies,[14] and it was not until Kerr succeeded Sproul as UC President that UC was able to evolve into a university system from 1957 to 1960.[15] At that time, chancellors were appointed for additional campuses and each was granted some degree of greater autonomy.[16]
