Vladimir Jakšić and Milan Nedeljković are the founders of Serbian meteorology. Many of their co-workers and meteorological observers have contributed to measuring meteorological parameters and recording development of the weather in the nineteenth century. They also described meteorological phenomena by simple words and sentences in some particular days on the margins of the paper. After doing the job, the observers were signed on the pages of record and so their names are preserved from oblivion. These additional observations and recordings represent the valuable contribution to the development of meteorology in Serbia. Former observers had no idea that their records made on pieces of paper become a historical value.
