Throwback Thursday Object: Perkins Details a Catastrophic Event from 1917 that Changed the Treatment of Blindness


On the morning of December 6th, 1917, a French cargo ship loaded with explosives collided with a Norwegian freighter in the harbor of Halifax Canada.  The resulting explosion killed about 2,000 people and the flying glass that resulted from thousands of windows blown out by the pressure wave injured the eyes of almost six thousand people and blinded 41 permanently.  The large number of eye injuries turned out to an important event in both medical care for eye injuries and rehabilitation efforts for people who are blind.  This week the archives at the Perkins School for the Blind commemorates the centennial of this awful event and its aftermath by posting documents that tell the story.  Perkins has several other online exhibits that are equally fascinating.

Throwback Thursday Object: An Early Math Aid


Our object this week is a wooden frame with small compartments in a twenty by thirty grid.  There are metal types with a raised Arabic numeral on the end that fit into the “cells.”  Originally called an Arabic Slate, this style of math aid was developed in Paris, France in the 19th century.  One source from 1910 called it the Paris Method.  This particular model, known as an Arithmetic Type Frame, was developed in 1936 at APH as an instructional aid for working problems in long division, multiplication, subtraction, and addition.   The supplied lead type was called Philadelphia Great Primer Type.  In 1959, APH introduced the Texas slate to replace the Arithmetic Type Frame.
