Mary C. Lyon, Radcliffe '50, will assume leadership of the '48 Signature editorial board, effective February 1, according to the announcement by the 'Cliffe publication yesterday. She succeeds Ireno C. Tinker, Radcliffe '49 as editor-in-chief.

Newly chosen College representatives to Signature are Norman J. Zierold '49, literary editor, and business manager George E. Ehrlich '49.

Filling the post of literary editor will be Muriel H. Michalover, Radcliffe '49, while Marion H. Eisendrath, Radcliffe '49, and Katharine D. Wadsworth, Radcliffe '50 were elected business manager and advertising manager, respectively.

Formerly Radditudes

Editor since origin of the publication in the fall of '46, Miss Tinker retires with the rest of the previous senior executive board. Signature was formerly titled Radditudes, and exclusively served 'Cliffedwellers. Last fall, however, it assumed its present name when it expanded to include the College.

When interviewed, Miss Lyon, who lives in West Bridgewater, stated that her election as the next Signature head "came as a little surprise." She added that the new staff will continue the policy of specializing the issues to certain themes. It will also concentrate on getting more and better material.
