Although more than 30 years have passed since their discovery, narrow-line Seyfert 1 galaxies (NLS1s) still present challenges for unified models of active galactic nuclei (AGN). Sources of electromagnetic emission at all frequencies, their physical properties and role in galaxy evolution remain poorly understood. The aim of this workshop is to present and to discuss developments in the field over the seven years since the most recent NLS1 conference (Milano 2011). The main topics of the workshop will include the multiwavelength properties of these objects from radio wavelengths to gamma rays, their role in AGN evolution, their relationship to other classes of AGN, and their place in the framework of AGN unified models. The workshop will be held at the Orto Botanico di Padova (Italy), the world's oldest academic botanical garden. During the event, a one-hour session will be devoted to the topic of gender balance in astrophysics. This session will be dedicated to Lucrezia Cornaro of the University of Padova, the first woman in the world to obtain a Ph.D. degree. We will commemorate the 340th anniversary of this event.
