==Last years and death==
Zedler probably created, or at least initiated further work. The ''Universal Lexicon'' article on Zedler published in 1749 says "he has several large works that are already being printed and should still come out".{{sfn|Gross Lexicon - Zedler|1749|pp=309-311}}
The influence of Zedler on further publishing projects is no longer detectable.
In the years up to 1751 the work of Wolf appears under or with the name of Heinsius.
For each Easter and Michaelmas Fair the firm published two volumes of the ''Universal Lexicon'', and at each of the Easter Fairs it published a volume of the ''General state, war, religious and scholarly chronicle''.
The alphabetical volumes of the ''Universal Lexicon'' up to 1750 were completed in this way.
Ludovici later expanded the ''Universal Lexicon'' by four supplementary volumes.

Zedler spent most of his last years on his estate near Leipzig.
The ''Universal Lexicon'' article on Zedler said that nevertheless he continued to provide useful advice to the firm.{{sfn|Gross Lexicon - Zedler|1749|pp=309-311}}
Zedler's sponsor Johann Peter von Ludewig had died in September 1743. Heinsius died in December 1750, and his company became known as "Johann Samuel Heinsius heirs". On 21 March 1751 Zedler also died, as recorded in the grave register of Leipzig.{{sfn|Quedenbaum|1977|p=305}}
His widow Christiana Dorothea left Leipzig in 1754 and moved back to Freiberg. She died soon after on 18 November 1755.
Her marriage to Zedler remained childless.
