Horace Jansen Beemer (c. 1845 – July 22, 1912) was an American railway contractor and businessman active in Canada.
There is little known of Beemer before he came to Canada in the 1870s and was employed on the Welland Canal.
He was soon involved in contracts of his own including a municipal water system in Quebec City[1] and a railway contract with the fr:Quebec and Lake St-John Railway.
After that time, his activity and influence diminished.
While Horace Beemer never became a top level decision-maker and financier, he did contribute substantially to the construction of railways and operation of related businesses.
