Since the mid-1880s, Brant Lake has been a popular fishing and hunting area among wealthy visitors, including
Theodore Roosevelt.
Circa 1900, several hotels began catering to these wealthy visitors. Summer camps for youth were established around the same time.
Brant Lake Camp was incorporated by R.B. Gerstenzang, J.E. Eberly, and John F. Malloy in 1917. The camp was featured in
Town & Country magazine. Brant Lake Lodge was one of oldest hotels in the area of the
Adirondacks; it burned down in April 1925. Brant Lake has had a post office and postmaster since at least 1892. The seat of government of the Town of Horicon is located in the hamlet. Brant Lake is also notable for being the site of North America's first
gerbil colony, which was established at Tumblebrook Farm in 1954 by Dr. V. Schwentker. ==Geography==
