Basic information
Positions count by year
Hover over a name to see the position and date range. This table only
includes positions where at least the start date is known. The positions count
can count the same person multiple times if they held different positions;
similarly, the list of staff may include the same person multiple times if
they held more than one position during a single year.
For each year, a person is included if they were at the organization for any
part of the year; this means the actual staff count at any point during
the year can be lower (or higher, if some staff held multiple positions in a
single year).

Full history of additions and subtractions
This table shows the full change history of positions. Each row corresponds
to at least one addition or removal of a position. Additions are in green and
subtractions are in red. If a position name changed,
it is listed simultaneously as an addition (of the new name) and removal (of
the old name) and colored yellow. Additionally there are faded variants of each
color for visited links.
