1937 Obituary 
ARTHUR MOLYNEUX SILLAR, M.B.E., had probably the longest professional experience of any consulting electrical engineer in London. He was associated with the electrical industry from its early days. After his education at Shrewsbury School he commenced his apprenticeship in 1881 in the Jablochkoff Electric Light Company's works, on the Albert Embankment, Lambeth. Later he was appointed chief engineer of the firm's successors, the United Electrical Engineering Company. He was also associated with the running of one of London's first electricity supply stations, in Belvedere Road, Lambeth, from which, by means of cables across Waterloo Bridge, the lighting of Covent Garden Theatre and a number of buildings in the Strand, was effected. Mr. Sillar then went into partnership with Mr. R. Venner, inventor of the time switch, and in 1894 he went into business as a consulting engineer, shortly afterwards becoming a partner in the firm of Lacey, Clirehugh, and Sillar. The firm was later known as Messrs. Lacey, Sillar, and Leigh.
Eventually Mr. Sillar carried on the business on his own account, and was actively engaged in it until his death, which occurred on 6th March 1937, at the age of 72. During his forty years of consulting work he designed and inaugurated electrical power systems for a large number of important municipal bodies and other companies at home and abroad. He also had a wide experience of tramways and light railways and was retained as a consultant by the London and North Western Railway. In addition he was consulting engineer to the Post Office and to the London Chamber of Commerce. During the War he assisted the Government in the Metropolitan and south eastern areas, also in East Anglia and the Midlands, and was appointed director of National Gauge Factories, under the Ministry of Munitions. For his services he was awarded the M.B.E. Mr. Sillar was elected a Member of the Institution in 1898, and was also a Member of the Institution of Civil Engineers, and of the Institution of Electrical Engineers. He was twice elected chairman of the Association of Consulting Engineers, and was a past-president of the Association of Supervising Electrical Engineers.
