Sub-Centre chairman Fred Seddon was the Deputy Area Engineer for the Sheffield Area of the Y.E.B.

Fred Seddon became Area Engineer when the load on the Sheffield system, which was the second largest electrically in the country, was doubling every ten years. He was a very staunch supporter of the IEE and strove for electrical Engineering professionalism in the true sense of the word. Applicants for engineering posts in Sheffield were required to be members of the IEE and those who wished to progress Fred Seddon were encouraged to attend lectures, indeed they had to keep up with advancing technology. There had always been a large percentage of Sub-Centre membership from the electrical supply industry and this percentage probably reached its peak about this time. Fred was not only chairman of the Sub-Centre but also Honorary Treasurer from 1959 to 1962 and was the local representative of the Benevolent Fund from 1962 to 1977. He was very disappointed the first two applications for Centre status had been unsuccessful and was the elder statesman on the working party for the third application.

Sheffield Sub-Centre, made its second application for Centre status to the Council of the IEE, this will eventually be rejected again following some heated exchanges with Savoy Place.

13th September, Minutes of Council Meeting contain the following reference to the Sheffield application for Centre status.

"Sheffield Sub-Centre

The Committee have received a Petition signed by 141 Corporate Members in the area of the Sheffield Sub-Centre asking that separate status as a Centre be accorded to the present Sheffield Sub-Centre.

The Committee have reviewed the case presented but before making a report on the matter they wish to consult with the Committee of the North Midland Centre, the present parent Centre.

The Council Supported this proposal".

23rd May, Minutes of Council Meeting contain the following reference to the Sheffield application for Centre status.

"Petition of the Sheffield Sub-Centre

The General Purposes Committee had deferred the submission of a recommendation on the Petition for Centre status received from the Sheffield Sub-Centre in September last, pending the findings of the Study Committee on Local Centre Organisation, in case anything emerged there from which might affect the view they had already formed that they could not support the Petition.

The Committee now find no reason to change that view, and accordingly they submit that the Council should not at this juncture convert the Sheffield Sub-Centre into a separate Centre.

The Chairman of the North Midland Centre confirmed that, although his committee had supported the Petition, they appreciated that the matter had received full consideration and did not wish to oppose the recommendations of the General Purposes Committee. The Council accepted the recommendation that Centre status should not be granted to the Sheffield Sub-Centre at this stage".

26th June, Sub-Centre committee meeting. The rejection of the application for Centre status was hotly discussed at this meeting. The Hon Secretary was instructed to ask, for the Council's further guidance, the reason for this application being turned down. There was a feeling that the rules had been changed to prevent Sheffield gaining Centre status.

Sub-Centre chairman Dr Oliver I Butler, Senior Lecturer in the Electrical Engineering Department at Sheffield University.

J Sykes appointed as Honorary Secretary and served for the next two years.

20th November, Sub-Centre committee meeting minutes state the following on the subject of Centre status. Membership figures for Centre status meant that 3 or 4 Centres would soon be required. The rate of growth of members in Sheffield was less than other parts of the country. The smallest existing Centre has a membership of 642. There was clearly some animosity with Council and the general thought was that their object was to block the application.

18th December, Sub-Centre committee meeting minutes indicated that 4,200 applications had been received for the Faraday Lecture and some method of rationing was required.

Application made to Council of the IEE for the inclusion of part of North Lincolnshire into the Sheffield Sub-Centre. This was approved and in April 1958 at a meeting of members at Grimsby. The North Lincolnshire District had been formed. The meeting was attended by North Midlands Chairman A.J. Coveney and the Sheffield Sub-Centre Chairman Dr. O.I. Butler to welcome the new members. At a further meeting held at Brigg in June 1958, Mr H Peace was elected Convenor of the North Lincolnshire District and held this office for the next seven years. (See Appendix 6)
