Regarding Edgeworth:

«He was the founding editor of The Economic
Journal in 1891, and continued as editor for 35
years.»

Perhaps some minor revision will be needed here, 
considering the entries on Edgeworth and Keynes 
in The Biographical Dictionary of British 
Economists, (vol 1 p. 356 and vol.2 p. 637, respectively):

"[Edgeworth] was also the first editor of The 
Economic Journal, a role in which he continued, 
latterly as joint editor with John Maynard Keynes, until his death."

"in 1911 [Keynes] succeeded to F.Y. Edgeworth as 
editor of The Economic Journal"
