Question: What influential educator was from the country that the Rhine separates from the country where the Spectre scenes with Detlef Bothe were shot?

<P0-S0> a brief shoot at london's city hall was filmed on 18 april 2015, while mendes was on location. <P0-S1> on 17 may 2015 filming took place on the thames in london. <P0-S2> stunt scenes involving craig and seydoux on a speedboat as well as a low flying helicopter near westminster bridge were shot at night, with filming temporarily closing both westminster and lambeth bridges. <P0-S3> scenes were also shot on the river near mi6's headquarters at vauxhall cross. <P0-S4> the crew returned to the river less than a week later to film scenes solely set on westminster bridge. <P0-S5> the london fire brigade was on set to simulate rain as well as monitor smoke used for filming. <P0-S6> craig, seydoux, and waltz, as well as harris and fiennes, were seen being filmed. <P0-S7> prior to this, scenes involving fiennes were shot at a restaurant in covent garden. <P0-S8> filming then took place in trafalgar square. <P0-S9> in early june, the crew, as well as craig, seydoux, and waltz, returned to the thames for a final time to continue filming scenes previously shot on the river. <SEP> <P1-S0> In February 2015 over fifteen hundred extras were hired for the pre-title sequence set in Mexico, though they were duplicated in the film, giving the effect of around ten thousand extras. <P1-S1> In addition to the principal cast, Alessandro Cremona was cast as Marco Sciarra, Stephanie Sigman was cast as Estrella, and Detlef Bothe was cast as a villain for scenes shot in Austria. <SEP> <P2-S0> stagecoach was the first of many westerns that ford shot using monument valley, in the american southwest on the arizona -- utah border, as a location, many of which also starred john wayne. <P2-S1> scenes from stagecoach, including a famous sequence introducing john wayne's character the ringo kid, blended shots of monument valley with shots filmed on the iverson movie ranch in chatsworth, california, rko encino movie ranch, and other locations. <P2-S2> similar geographic incongruencies are evident throughout the film, up to the closing scene of ringo (wayne) and dallas (trevor) departing lordsburg, in southwestern new mexico, by way of monument valley. <SEP> <P3-S0> Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. <P3-S1> The river makes a distinctive turn to the north near Chur. <P3-S2> The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East. <P3-S3> This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). <P3-S4> Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. <SEP> <P4-S0> In time, some ideas from these experiments and paradigm challenges may be adopted as the norm in education, just as Friedrich Fröbel's approach to early childhood education in 19th-century Germany has been incorporated into contemporary kindergarten classrooms. <P4-S1> Other influential writers and thinkers have included the Swiss humanitarian Johann Heinrich Pestalozzi; the American transcendentalists Amos Bronson Alcott, Ralph Waldo Emerson, and Henry David Thoreau; the founders of progressive education, John Dewey and Francis Parker; and educational pioneers such as Maria Montessori and Rudolf Steiner, and more recently John Caldwell Holt, Paul Goodman, Frederick Mayer, George Dennison and Ivan Illich.
