Over the course of many years Boas often wrote notes to himself concerning leadership. Like a photographer who captures the moment, Boas documented moments that caused him to reflect broadly and insightfully upon issues related to leadership....

This article is divided into three parts. In the first part, Galit, Boas's spouse, chronologically reviews the five periods of Boas's professional life—describing what is special to each period and what connects them—while relating to the centrality of values and the secret of charisma according to Boas Shamir....

Signaling theory suggests that people use cues transmitted by leaders to form impressions of charisma but the validity of these impressions remains unexplored.

We argue that the sources of charisma are innate and can be explained as part of unique human cultural transmission mechanisms....

In the present research, we shed light on the nature and origins of charisma by examining changes in a person's perceived charisma that follow their death. We propose that death is an event that will strengthen the connection between the leader and the group they belong to, which in turn will increase perceptions of leaders' charisma....

Extending prior research on idiosyncratic deals (i-deals), in the current study we examine the functioning of i-deals in the context of leader-member exchange (LMX) differentiation....
