Emerson Electric ( EMR) said President James G. Berges will retire Nov. 1 after nearly 30 years with the company in order to pursue personal interests.

Farr will take on the additional title of president, and Berges' duties will be divided among senior management. Berges joined Emerson in 1976. Shares of Emerson were down 70 cents, or 1%, to $69.22.
