[1] Encyclopædia Britannica mentions about his youth: Messikomer dug peat for his mother’s kitchen fire, he dreamed of finding remains of the Helvetii, the Celtic inhabitants of Swiss lands whom Julius Caesar described.

[2] At the age of 22, he met the poet Jakob Stutz, and wrote his first poem published a year later in "Allmann", the predecessor of the present regional newspaper Zürcher Oberländer.

That's why he sold his farm to a neighbor on 26 September 1890, excluded the lands at the Robenhausen site where Messikommer had established the analogy to a present archaeological open air museum.

[2] Messikommer operated for two years on behalf of Professor Arnold Escher von der Linth in the preparation of the geological map of the Allman and the Hörnli mountain chains.

[6] On 2 February 1858 Jakob Messikommer discovered piles at low water level on Pfäffikersee lake shore, and thus initiated the systematic exploration of the settlement Wetzikon-Robenhausen whose research he headed to the 1890s.

Due to his reputation by his discoveries in Robenhausen, Messikommer was consulted by the canton of Thurgau to research "Pfahbauten" on Bodensee: 1861 on its Untersee area and 1862 during excavations in Niederwil.

Two years later Messikommer suspected, quite rightly, that the human remains in the so-called Renntierhöhle (literally "Reindeer cave") at Thayngen were older than his recent Neolithic discoveries.

In the NZZ newspaper, Messikommer published some contributions about "Das Gebiet in Wetzikon in prähistorischer Zeit", by explaining his recent archaeological perceptions to a wide audience.
