I know this list is not complete and anybody who can find any omissions could you please point them out. I made this list in research for a book i'm thinking about writing and for my own reference but i thought i would share it with you so feel free to copy and paste it. I include only the big 4 WBC WBA WBO IBF interim titles don't count but if upgraded to full title status and defended eg (Arthur) they appear. 1890 1891 Fitzsimmons 1892 1893 1894 Fitzsimmons 1895 1896 Fitzsimmons x2 1897 Fitzsimmons 1898 1899 Fitzsimmons 1900 1901 1902 Fitzsimmons 1903 Fitzsimmons 1904 1905 Fitzsimmons 1906 1907 1908 1909 1910 Joseph 1911 1912 1913 Sid Smith Ladbury 1914 Welsh Wells McCormick x2 Blake Ladbury P Jones 1915 Lewis x5 Welsh x5 Wells Lee 1916 Lewis x8Welsh x3 Wilde x4 Hughes Lee 1917 Lewis x2Welsh x2 Wilde Clark 1918 Lewis x5 Wilde 1919 Lewis x4 Heasman 1920 Wilde x4 1921 Lewis 1922 Lewis 1923 Wilde 1924 1925 1926 1927 Baldock Milligan 1928 1929 1930 Berg x4 1931 Berg x5 1932 Berg Harvey 1933 King Watson 1934 Tarleton 1935 Lynch 1936 McAvoy Harvey Lynch 1937 Farr Lynch x2 1938 1939 Roderick 1940 1941 1942 1943 Kane Paterson 1944 1945 1946 Paterson Curran James 1947 Monaghan 1948 Paterson Monaghan 1949 Monaghan x2 Allen 1950 Mills Woodcock (?)
