From 1883 to 1904 scientists lived and worked year round at the summit of Ben Nevis - observing the weather at 1,343metres (4,409 feet) above sea level was an extreme task. Three men pictured at the Observatory. From left to right - Angus Rankin, R.T. Ormond, R.C. Mossman. The first superintendent of the observatory was Robert Omond (centre), he was succeeded by Angus Rankin (right) in 1897 and Robert Mossman volunteered at the observatory from 1889 to 1891. The observers were supported by various support staff but life was generally very isolated.
