Slaby and O.
Slaby in Berlin shortly afterwards made a similar exhibition of syntonic electric wave telegraphy' O.
Lodge had previously described in 1897 a syntonic system of electric wave telegraphy, but it had not been publicly seen in operation prior to the exhibitions of Marconi and Slaby.'

Slaby and Braun were the most active.
Slaby paid considerable attention to the study of the phenomena connected with the production of the oscillations in the antenna.
When the methods for effecting this had been worked out practically it finally led to the inventions of Slaby, Braun and others being united into a system called the Telefunken system, which, as regards the transmitter, consisted in forming a closed oscillation circuit comprising a condenser, spark gap and inductance which at one point was attached either directly or through a condenser to the earth or to an equivalent balancing capacity, and at some other point to a suitably tuned antenna.
The inventions of Slaby, Braun and others were put into practice by a German wireless telegraph company, and very much work done in erecting land stations and equipping ships.
Forms of open circuit wave meter have been devised by Slaby and by Fleming.
