  Eric H. Strach (1914-2011) studied medicine at University of Prague and
graduated in 1938. Strach dedicated a great part of his life to astronomy
becoming a consistent and meticulous observer. He joined the Liverpool
Astronomical Association and British Astronomical Association during the 1960s
and obtained two recognitions as proof of his great work in solar physics: the
BAA's Merlin Medal and Gift in 1999 and Walter Goodacre Medal and Gift, ten
years later. Strach recorded four decades (1969-2008) of systematic solar
records in his observation notebooks although he started his observations from
the late 1950s. In this work, we document the valuable effort made by Strach in
getting four decades of solar records and the importance of this kind of long
observation series for studies of space weather and climate. We present the
sunspot group number series according to Strach's data and a long observation
series of prominences recorded by Strach.
