In honour of his 50th anniversary, scholars, architects, merchants, writers and friends gathered for lunch on 9 December 1842 in a daytime restaurant in Berlin.
The room was decorated by the royal landscape and theater decoration painter Johann Karl Jakob Gerst (1792–1854) with the Portrait of Sachs under Flower garlands.
Part of the table decoration had the shape of the Sloping Tower of Pisa, with the inscription "Sachs' indestructible Pisébau".
Among the dinner speakers and guests were community leader Joseph Lehmann, editor of the magazine for foreign literature, Dr. Löwe as organizer of the festival and Prof. Wilhelm Stier.
Stier had been trained by Solomon as a student of the Bauakademie in 1816 and they had become friends.
 Another speaker was the writer, philosopher, bookseller and humorist Dr. Louis Weyl. (*
23 April 1817; † 9 September 1851).
With his humorous lecture on the arts, especially architecture, and a table song, he delighted the society.


On 22 December 1842 Sachs celebrated his seventieth birthday.


Sachs' varied literary activities continued in 1844.
His astronomical writings – Achsenparallelismus und Sonnensystem, i.e. parallelism of axes and the solar system, appeared in Berlin in 1850, but were not as successful.
However, his two self-developed illustrative models for teaching, the "Diagonon" and the "Cylindrical Ellipto-Tellurium", are to be praised.
In 1845, Solomon wrote a pamphlet On the existence of air and water pressure, which was directed against Friedrich Johann von Drieberg.
