Mendeleev was working on a text book to use with his students.
No, Dmitri Mendeleev in Russia developed the first periodic table.
1869
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.

Dmitri Mendeleev is credited with developing the periodic table of elements in 1869. He arranged the elements by increasing atomic mass, grouping together elements with similar properties. Mendeleev's table formed the basis for the modern periodic table.
Dmitri Mendeleev created the periodic table of elements, arranging elements by atomic mass and properties. His contribution revolutionized the field of chemistry by predicting the existence and properties of undiscovered elements. Mendeleev's periodic table provided a framework for understanding the relationship between elements and laid the foundation for modern chemistry.
Mendeleev's prediction that there were elements missing from the periodic table was confirmed when gallium was discovered in 1875 and germanium in 1886, fulfilling the gaps Mendeleev had left in his periodic table.
Dmitri Mendeleev created the periodic table to organize and classify the known elements based on their properties and atomic weights. He left gaps for undiscovered elements and successfully predicted the properties of some of these missing elements.

Sperm is not an element and therefore does not form any part of the periodic table.
Dmitri Mendeleev is credited with putting together the first periodic table in 1869. Mendeleev arranged the elements based on their atomic mass, and left gaps for undiscovered elements which he predicted would fill those spaces.
