In addition to his own activity as a chemist, Speter had a great interest in the study of the history of chemistry. The title of his doctoral dissertation, publish 1910, was "Lavoisier and his Forerunners"
. Later he studied various areas of chemistry, but his main interests were in the histories of sugar and superphosphate.
The history of sugar production. 
Speter studied the work of the two people who are considered the founding fathers of the production of sugar from  sugar beets:  Andreas Sigismund Marggraf  and Franz Karl Achard.   He published a comprehensive bibliography of Franz Karl Achard`s contributions, including more than 200 references, in the journal of the German sugar industry ("Die deutsche Zuckerindustrie"). He also published an illustrated account of Achard`s experiments in beet sugar production. Speter also studied other, less successful, efforts to produce sugar. The famous Justus von Liebig prepared sugar from 7 different species of maple and recommended extensive planting of maples in hope of making Germany self-sufficient in this respect. Another German, Ludwig Hofmann, tried to produce sugar from pumpkin.
Speter also studied and wrote about some more esoteric historic experiments with sugar. In 1932 he described the experiments with sugar Triboluminescence made by Francis Bacon and Otto von Guericke. In another publication, he described an anonymous German author who, in 1780, prepared Leyden jars where melted sugar served as an insulator.
 The history of superphosphate.
In his study of the history of Superphosphate Speter collected information, including patents and notes, about 16 scientists and industrialists who contributed to the research and manufacture of the fertilizer. They include: Johann Tholde,  a school principal from Brno; Johan Gottlieb Gahn; Carl Wilhelm Scheele; Anders Gustaf Ekeberg; A. Bergsteen; Louis-Nicolas Vauquelin; Antoine Fourcroy;  George Pearson; Sir  Humphry Davy; S. F. Hernbstädt; Justus von Liebig; Sir John Bennet Lawes and Sir James Murray (physician). The results of his studies were published in "Super-Phosphate", a monthly journal of the International Superphosphate Manufacturers' Association. The papers included detailed bibliographies and biographical notes.
 The history of the match.
As a by-product of his interest in the history of superphosphate he became interested in another Phosphorus product, the match, and its predecessor the tinderbox. In the "Deutschen Zündwaren-Zeitung", the journal of the German match industry, he published an article about the matches of  John Walker called "Congreves" or "friction lights". In the same journal he published an illustrated history of matches based on a translation from Hungarian.  He also republished an early 19th-century account about tinderboxes, by Friedrich Hermbstädt.
Other topics in the history of chemistry.
Speter studied a variety of other topics in the history of chemistry, among them: plastic materials, explosives, materials for the photographic industry, Scientific instruments and life-saving equipment. The results of his studies were published in German and Austrian scientific and industrial journals. Translations also were printed in publications in the United States, The Netherlands and Hungary.
