56. Yes. I can name three: Patrisse Cullors. Opal Tometi. Alicia Garza.

They are the founders of the movement.

As to your questions, the movement is not entirely decentralized--they have a unified web page, a facebook page (where a lot of angry Sanders supporters are making fools of themselves), a twitter account, and they've been at this for three years, now. You can find the answers to many of your questions HERE: http://blacklivesmatter.com/ and they even have a contact page.

Symone Sanders self-identifies as a SUPPORTER, not an activist for the movement. She had a paying job at Public Citizen.

Her current job is incompatible with being an activist for the organization:

#BlackLivesMatter Statement on Political Affiliations
by BlackLivesMatter | Aug 10, 2015 | Press Releases, Uncategorized | 0 comments
FOR IMMEDIATE RELEASE
August 9, 2015
At this time, #BlackLivesMatter does not endorse any presidential candidate. Moreover, we are not affiliated with a political party. Our work is not funded or driven by any political party nor is it influenced by local or national candidates.
As stated in our mission, #BlackLivesMatter is an ideological and political intervention; we are not controlled by the same political machine we are attempting to hold accountable. In the year leading up to the elections, we are committed to holding all candidates for Office accountable to the needs and dreams of Black people. We embrace a diversity of tactics. We are a decentralized network aiming to build the leadership and power of black people. We do not endorse any political party and we are not supported by any political party. Our political aims we’ve stated clearly.
Historically, all political parties have participated in the systematic disenfranchisement of Black people. Anti-black racism, especially that sanctioned by the state, has resulted in the loss of healthy and thriving Black life and well-being. Given that, we will continue to hold politicians and political parties accountable for their policies and platforms. We will also continue to demand the intentional dismantling of structural racism.
For more information about #BlackLivesMatter nationally, please visit the official website at www.blacklivesmatter.com, follow @BlkLivesMatter on Twitter, or visit the Facebook page here.

They didn't just spring up out of nowhere. It's just that white America hasn't bothered to pay attention to them up to now.
