1934 Obituary 
EDGAR ISAAC EVERETT was a pioneer in the development of electrical measuring instruments.
He was born at Metfield, Suffolk, in 1869 and in 1882 became an apprentice at the Cambridge Instrument Company's works.
In 1896 he founded the firm of Messrs. Everett and Company, with premises in Albemarle Street. He shortly afterwards moved to Charterhouse Square, and in 1900 was joined by Col. Kenelm Edgcumbe, when the firm became Messrs. Everett, Edgcumbe and Company. Owing to expansion of business a site was selected at Hendon, and new premises were erected in 1905. The business was formed into a limited liability company in the following year.
Mr. Everett was responsible for the development of the ohmmeter type of movement, a leakage indicator, inkless recording instruments, and reverse relays. During the War he successfully investigated the manufacture of control springs for electrical instruments, as Continental supplies had failed.
In addition he was keenly interested in aviation and shortly after Bleriot flew over the Channel he constructed an aeroplane at Hendon, which he tested in a field reserved for the purpose. From this field Paulhan made his classic flight to Manchester; the ground is now part of the Hendon Aerodrome.
In 1928 Mr. Everett retired from active management of the company and lived at Cooden, Sussex, where he died on 19th April 1934.
He was elected a Member of the Institution in 1919, and was a member of the Committee of the Southern Branch at the time of his death. He was also a Member of the Institution of Electrical Engineers.
