Rennies Flour Mills [1905-1908]
Fortunately, reader Zerocube wrote in to correct me:
Alfred Herbert Rennie did not hang himself. In fact, he jumped off a boat. He had a boat for him to commute between central and his factory. The name has been there before Rennie died.
This website has more on the story, and says:
The Mill started operation in 1905 and closed in April 1908 because of high production cost and poor quality of product. The failure in business had made Mr. Rennie so disappointed that he jumped into the sea and drowned himself at Lei Yue Mun, 3 km from his flour mill on 14 April 1908.
The details of Rennie's death are confirmed in the April 14, 1908 edition of the China Mail. It had an article 'Death of Mr Rennie. Body found in Harbour" which includes the text:
Just as we go to press we learn that the body of Mr. A. H. Rennie, manager and founder or the Junk Bay flour mills, was found floating in Lyeemoon Pass this afternoon.
We now understand that Mr Rennie accidentally fell overboard from his launch, Canada, whilst going to Junk Bay, and his body was picked up by the launch after a search.
I've used the dates 1905-8 given above, though they may need to be corrected later. A map dated 1939-40 (Plate 2-12, Mapping Hong Kong) still shows a building at this location, labelled "Rennies Flour Mills".
