Unlike his brother Nikolai, who directed his attention to the specific topic of church architecture, Fedor turned his to a region, Vilna. He taught there, worked in digs there, and involved himself with the Archeological Museum, writing a guide to it. In addition to drafting an archeological map of Vilna Province, he made one also of Grodno Province.
Nevostruev was one of the first archeologists to come from Viatka, just as he was also among the first trained in theology to develop church archeology as a branch of the science. His primary contribution was the cataloging of Slavic manuscripts in the Synodal Library, which won him the Lomonosov Prize, but he also excavated in the Ananinskii Mogilnik.
Trying to categorize Garkavi is as problematic as deciding which name to use: Avraam/Albert Yakovlevich Harkavy, Авраа́м Я́ковлевич Гарка́ви, or Avraham Eliyahu ben Yaakov Harkavy. History and Wikipedia emphasize his importance as a scholar of Judaism, but that narrows the breadth of his focus and his importance to archeology, especially in decoding manuscripts, especially sources written by Arabic travellers. An Orientalist, he headed the Oriental section at Publichka. There is no immediate tag for someone who was both active in the Jewish community and rose through the ranks to become a member of the Russian hereditary nobility.
The son of a priest from Vologda Province, Pavel Ivanovich finished his Master’s in 1837 at the St. Petersburg Spiritual Academy, on Ancient Jewish Synogogues. Discovered by historian Mikhail Pogodin, Savvaitov enjoyed a splendid career as a teacher of Russian libterature in both military and commercial schools. His most famous work was a hermeneutical study of the Bible, and his best known contribution to archeology was Description of ancient royal utensils, clothes, weapons, military armor, based on the collection in the Moscow Armoury. He also wrote Travels of the Novgorod Archbishop Anthony to Constantinople at the end of the 12th century and published copiously on the monasteries of his native Vologda. He also published on Finno-Ugric (Zyrian) linguistics.
