226 Marine Exposition in New York—Nov. 9-14 Marine week next Nov. 9-14 will bring to New York City every import- ant group of marine men. In the first place the marine exposition, to be held at this time in the Two Hundred and Twelfth Anti-Aircraft Regiment arm- ory at Sixty-second street and Colum- bus avenue, New York, will bring out new developments in all branches of the industry which will attract the notice of everyone interested in the repairs building and operation of ships. Among those who have arranged conferences are the Society of Naval Architects and Marine Engineers, the American Marine Standards commit- tee, the American Society of Marine Designers, the American Steamship Owners’ association, the Council of American Shipbuilders, the National Marine Engineer’s Beneficial associa- tion, the Ocean Association of Marine Engineers, the Port of New York Au- thority, the Neptune Association of Masters and Mates, the Maritime As- sociation of New York, the New York Tow Boat exchange, the Propeller club, the United States Ship Operators’ association and others. Attendance at previous marine shows has averaged more than 25,000, and a still large number is expected at the next event. More than 70 per cent of the space at the Two Hundred and Twelfth Anti-Aircraft armory, where the show will be held, has al- ready been sold. P. A. Sensenig, chairman of the ex- hibits committee, said that there will be discussions of marine problems at the meetings, which will be held sever- al weeks before congress convenes in Washington. Louis M. Ross, who has been traf- fic representative for the Dollar Line in Boston, has resigned to become associated with the car service divi- sion of the American Railway asso- ciation, which will open offices in Boston at 131 State street. MARINE REVIEW Elmer A. Sperry Honored On April 30 word was_ received that Elmer Ambrose Sperry, inventor of the gyro-compass, had been elected to life membership in the National Academy of Science, Washington, D. C. This well deserved recognition rep- resents one of the highest honors that can be conferred on a scientist in our country. Membership in this organ- ization is limited in number and at the present time consists of about 100. Election to the Academy accord- ing to a long established custom comes to the recipient without prior knowledge and is awarded for dis- tinguished accomplishments in science or art which contribute to the better existence of the people of the world. Including Mr. Sperry, only 17 engi- ELMER A. SPERRY neers have been so signally honored. Founded during the civil war by an act of congress signed by President Lincoln, the National Academy of Science served as a means of bring- ing the scientific strength of the na- tion to the aid of the government. Ever since it has faithfully fulfilled the purposes of its origin. During the late war this body received recognition by President Wilson in an executive order continuing the National Re- search Council which it had organized to help prosecute the war to a suc- cessful conclusion. Though not a marine man in the ordinary meaning of that term, no name is more .generally known on board ship and in maritime circles than that of Elmer A. Sperry through his invention and perfection of the gyro-compass, by means of which the true course of a ship may be noted June, 1925 without fear of disturbing magnetic influences. Mr. Sperry has been ex- traordinarily active throughout his life from early boyhood to the present time and has a most remarkable rec- ord of accomplishment in_ several branches of engineering. It is said that he has over 400 patents to his credit. Many of these inventions have been of unique and startling promise, since his first are light, made in his early youth, up to his present successful work in navigation. Of these the outstanding are, the high intensity are light making possible the world’s largest searchlight with its billions of candle power, the gyro- stabilizer for reducing the rolling of ships, and the gyro-compass as an instrument of precision for determin- ing the true course in navigation. Mr. Sperry is president of the Sper- ry Gyroscope Co., Brooklyn, N. Y., a member of the Society of Naval Architects and Marine Engineers and of many other important engineering societies. George J. Robinson Retires The retirement from active duty of George J. Robinson, president of the Robins Dry Dock & Repair Co., on account of ill health was announced recently by the Todd Shipyards Corp. of which the Robins company is a sub- sidiary. Mr. Robinson has been actively as- sociated with William H. Todd, presi- dent of the Todd Shipyards Corp. for GEORGE J. ROBINSON the past thirty years and is one of the best know ship repair men in the country. During that period he rose from rivet passer boy to be .
