Nordheimer Ravine
From a family of Jewish Bavarian merchants, Samuel Nordheimer immigrated to Toronto from Bavaria in 1844. With his brother, Abraham, they imported pianos and by 1890 opened a factory in the Junction, to become one of Canada's best known domestic piano brands.
A great music promoter of the 19th century, he supported musical societies and clubs, opened concert halls, and directed the Toronto Philharmonic Society. After demolishing Warren Baldwin's home, Russell Hill, he built Glenedyth named after his wife and dammed Castle Frank stream to create ponds and a waterfall. In 1928, Heintzman & Co took over A & S Nordheimer, and a year later, Glenedyth was demolished.
The Nordheimer ravine was buried in the mid-1970s, when the Spadina subway line was built. Like many other rivers and creeks along St. Clair, it now flows through a storm sewer.
