On suetterlin (or the overall topic of current) its not just a change about handwriting. At the beginning of the 20th century, most German books were published in blackletter (Fraktur) until it was abolished by the Nazi regime (internal reasoning "you cannot rule the world if the world cannot read what you type", what was communicated "Fraktur is jewish"). I think the scandinavian countries had similar changes, maybe sometimes a bit earlier. For handwriting there had been going on a debate on whether to use Kurrent (Sütterlin is a Current) or Antiqua for centuries. Hermann Hesse mandated for years that his German books still should be printed in Fraktur, until at one point someone convinced him that young people would not pick them up anymore. Overall German orthography never quite recovered from the switch to Antiqua, because the sz ligature in Fraktur was not directly mapped to "sz" in Antiqua instead the letter ß was introduced, but the Swiss used French typewriters so they use "ss" instead.
