Apparently the prize was presented at the famous Paris Exhibition of 1889, at the time of the construction and indeed completion of the Eiffel Tower. Family tradition is that it was 'father and son' who went, representing the firm of Tate & Lyle, in which they had been involved from the start of the Liverpool Refinery. Sadly Crawford succumbed to the Sugar Industry's sickness of alcoholism (see my blog of 26th November last) and ended up in the Union Infirmary (former Walton Workhouse) where he died on 8th July 1907, aged 70. His wife had died there (aged 63) exactly a year before. Although most of the records of that Institution have disappeared, family memory is that (probably in his last year) his daughter Agnes would bring him to her home on a Sunday for his roast dinner. It was she who undertook the responsibility of burying him.
It is said that Crawford was a member of the Royal Black Institution, an organisation related to the Orange Order but owing its origins to the Scottish Masonic Order. The 'Blacksonites' were considered to be more religious than political and more 'respectable in its proceedings' than the Orange Order (see Wikipedia Article).
