Electroanalytical techniques:

Past, present, and future of applications of electroanalytical techniques in analytical and physical organic chemistry (J. Solid State Electrochemistry. 2011. V. 15. P. 1753-1759), authored by Petr Zuman

With the drop of mercury to the Nobel Prize (Electrochemistry, Past and Present, ACS Symp. Ser. 390. 1989. Chapter 23. P. 339-369), authored by Petr Zuman; illustrated by many rare photos, incl. one of P. Delahay (Fig. 11); the starting point of the history of polarography is ca. 1918, but Heyrovský biography is also presented starting from his birth in 1890

Development of pulse polarography and voltammetry (Electrochemistry, Past and Present, ACS Symp. Ser. 390. 1989. Chapter 25. P. 380-395), authored by Janet Osteryoung and Carolyn Wechter; the story starts from 1930, but active development becomes possible ca. 20 years later, when commercial instruments appeared

Coulometric Titrimetry (Electrochemistry, Past and Present, ACS Symp. Ser. 390. 1989. Chapter 27. P. 402-416), authored by Galen W. Ewing; the earliest works refer to 1910s

History of electroanalytical chemistry in molten salts (Electrochemistry, Past and Present, ACS Symp. Ser. 390. 1989. Chapter 28. P. 417-428), authored by Herbert A. Laitinen; the earliest works refer to 1910s

Impedance

Reflections on the history of electrochemical impedance spectroscopy (Electrochim. Acta. 2006. V. 51. P. 1376–1388), authored by Digby D. Macdonald

In situ combined techniques:

Spectroelectrochemistry using transparent electrodes. An anecdotal history of the early years (Electrochemistry, Past and Present, ACS Symp. Ser. 390. 1989. Chapter 30. P. 442-457), authored by William R. Heineman and William B. Jensen; earlier story with in situ optical studies of electrode surfaces (started from 1929) is mentioned with Refs, but the main topic is spectroelectrochemical study of events in solutions (started only from 1960s)
