Update: The final list has been published.

A few weeks ago, Planetizen put out a call for nominees for the title of "Most Influential Urbanist," and via Facebook, Twitter, and email, our audience produced almost 200 nominees.

We added an extra layer of consideration to the request: that the 2017 version of this crowdsourcing activity reflect the diversity of the many related fields of urbanism—both in demographic considerations like age and gender, and also in the many forms that urbanism can take. In doing so, we hoped to produce a list of nominees that broadens the discussion about what it means to influence the future of cities and communities.

There again, the audience delivered, and the list below is much more inclusive than our previous effort at crowdsourcing a list of "Top Urban Thinkers." It's clear that the Planetizen audience is ready to change the focus of the urbanism discussion.

Now for the fun part. We have created a survey that allows anyone and everyone to rank the "Most Influential Urbanists" from the following list of nominees. Here are a few suggestions as you do so: After clicking the link below, you'll see a Survey Monkey form with all of the names shown below. Please select only the names that you strongly believe should be included on a list of "Most Influential Urbanists." After you select these nominees, you'll have a chance to rank them in order. If you see a name on the list that you aren't familiar with, or one that you feel strongly should not be on the list, leave them off your selections. If you believe urbanism should have strict definitions, or that some characters in history have received more credit than they should, your omissions are the way to express those opinions.

Meanwhile, we hope the list below will serve as a continued resource for people to explore new ideas and historic practice of urbanism. Even the most seasoned and studied urbanists out there will find something new to learn from exploring the list and digging further into the history and accomplishments of the 200 nominees listed below.
