I will review our current knowledge of soft gamma repeaters (SGR) and anomalous X-ray pulsars (AXP), two peculiar classes of pulsars believed to be 'magnetars', i.e. neutron stars powered by a huge magnetic field. Recent studies of transient events from SGRs and AXPs allowed a large jump in our understanding of these objects, although they also prompted new unanswered questions. In particular, the recent discovery of a low magnetic field magnetar is causing a re-think of some of the basic ingredients of the magnetar model.
The Square Kilometre Array is intended to be the centimeter- and meter-wavelength telescope for the 21st Century. Originally proposed as the "hydrogen telescope," the science case is now recognized to be much broader, and the SKA will address fundamental questions in astrophysics, physics, and astrobiology. The international science community has developed a set of Key Science Programs: (1) Emerging from the Dark Ages and the Epoch of Reionization; (2) Galaxy Evolution, Cosmology, and Dark Energy; (3) The Origin and Evolution of Cosmic Magnetism; (4) Strong Field Tests of Gravity Using Pulsars and Black Holes; and (5) The Cradle of Life & Astrobiology. I highlight how the SKA's Key Science Programs will be an integral component of the multi-wavelength, multi-messenger frontiers for astronomy and how the science pathfinding for the SKA is beginning now.
In this talk I will summarise the events that led to the discovery of the first four pulsars, recount several instances where pulsars were almost discovered and reflect on what lessons we might draw from these stories.
