In brief
Important Contributions:
Description:
- John
Franklin-Adams, a wealthy English amateur, gave this telescope
as a gift to the
Republic Observatory
(then known as Government Meteorological Observatory).
It was known as the twin telescope because it had two telescopes
(6 inch and 7 inch) on the same mounting.
- During
1962 -1964 a new office block with a library was erected
with two domes on its roof. The
Reunert
and Franklin Adam twin telescopes were moved here. [Hers]
