Club History

A Brief History of the Minnesota Mineral Club

The Minneapolis Mineral and Gem Club was organized in 1935 as a Science Museum Society of the Minneapolis Public Library Museum and continued formally until early 1942. Members who remained in the cities during the war continued to meet informally at private homes.

In late 1945, William Bingham, the last formal president of the Minneapolis Mineral and Gem Club, convened a meeting at Pillsbury Hall on the University of Minnesota campus. Five of the thirteen attendees agreed to serve on a constitutional committee to establish a new Club.

The Actual MMC Forms ...

The first official meeting of the newly formed Minnesota Mineral Club was convened on December 8, 1945 at the home of Mr. and Mrs. Bernard Dahl. Half of the 26 attendees became official members that night and selected a slate of seven initial officers to serve until the first annual meeting, to be held on March 9, 1946 at the Curtis Hotel in Minneapolis. Sixty-six members attended the first meeting.  Of these, 43 were active members; 22 were associate members and one, Dr. H. C. Hake, of Portland, Oregon (editor of the Mineralogist Magazine), who helped organize and name the Club, was elected an honorary member. William Bingham was elected as the Club’s first President and served in that role to 1948.

The Club’s first annual exhibit (show) was held on Saturday, April 14, 1946 at the Curtis Hotel. Twenty-six members provided exhibits, which were judged competitively. The first issue of the Rock Rustler’s News was published in May 1946. The first field trip, to collect near Stillwater, was held on May 12, 1946.

Members of the Minnesota Mineral Club (MMC) visited the Minneapolis Convention of the Midwest Federation of Mineralogical Societies in October 1946 and joined the federation that year. (Since then, numerous members of the Club have served both the Midwest and American Federation in various leadership roles.)

The Next Steps ...

The Minnesota Mineral Club was officially incorporated on February 15, 1950.

The MMC hosted the Midwest Federation Convention at Macalester College in 1952 and the American Federation Gem and Mineral Show at the State Fairgrounds in July 1956 and also hosted the Midwest Federation Conventions in 1970, 1982, 2003 and 2012.  Four MMC members have served as President of the regional group and three were recognized as honorary members of the region:  William de Neui and Bill and Jean Dahlberg.

Bill deNeui is one of the founders of the American Federation Scholarship Foundation and served as its first Treasurer.  He is also responsible for registering the Foundation as well as the MWF and the AFMS as Minnesota corporations.  A member of the MMC serves as the official registrar for these corporations.

Minnesota's State Gemstone ...

MMC members successfully lobbied the state legislature to have the Lake Superior Agate named as the state gemstone.  This is just one aspect of the Club’s love affair with Lakers.  In 1988, the Club hosted the “Night of the Lake Superior Agate” where members and guests could actually see some of the more famous Lakers and hear from agate author, Club member Scott Wolters.  In 1995, Night of the Agates II again brought many local agate lovers together for an all agate exhibit and presentation.  “A Celebration of Agates” show, sponsored by the Club, was held in 2012.

Club member Mike Carlson created the large format book “The Beauty of Banded Agates” with photos by fellow Club members Pete Rodewald and Dennis Westman. Pete and Mike, along with member Larry Costigan and his son Brian, were invited to participate in the International Agate Show held in Munich, Germany in October 2005.

Naming New Finds ...

The Minnesota Iron Ranges provided rewarding collecting sites while the mines were operating and owners were less concerned about security and potential lawsuits.  MMC members collected there often, especially on the Cuyuna Range near Rabbit Lake.  Bill Bingham found a red and yellow fibrous silicate with inclusions of goethite, which is now known as Binghamite, a variety of Quartz.  Another Club member, Ray Lulling later found a more opaque and more coarsely fibrous quartz material, which he named Silkstone, after determining it was indeed different than Binghamite.

The Gavels ...

Ray Lulling, of Silkstone fame, was better known for his lapidary work.  In the early 50s he fashioned a Club gavel with the appearance of an Estwing rock pick.  The hammerhead is Binghamite and the handle is bands of Minnesota minerals.  It is encased in a leather sheath with a Thomsonite button.  The gavel is presented to each incoming president and displayed during the Club’s annual banquet.

Following a discussion on the need for a device for calling Midwest Federation meetings to order, William de Neui fashioned a traditional gavel head out of Wyoming jade and inscribed the dates 1940 – 1960, in celebration of the first twenty years of the federation.  A local woodworker fashioned the handle for the gavel. De Neui also made a small case to protect the gavel.  This gavel is also presented to the incoming Midwest Federation president each year.

Moose Lake Agate and Geological Interpretive Center


Thanks to the dream of one determined man, the Moose Lake Agate and Geological Interpretive Center at Moose Lake State Park is a reality.  Dedicated in 2004, the center is devoted to Lake Superior Agates and minerals of Minnesota.  The Club contributed funds toward the showcases in the center and various members lent or donated pieces from their collections.  MMC member Phil Gotsch championed the cause across the state and encouraged local Clubs to work together to create MAGIC.

Mineral Boxes ...

What to do with all those rocks?  During his term as Publicity Chair, Dennis Westman decided that local schools could use the MMC’s surplus and the MMC could reach potential rockhounds.  With the Club’s blessing he created fifteen mineral boxes and gave them to local teachers.  Each year, he would make fifteen more boxes and give them to teachers.

The Science Museum of Minnesota offered the MMC an opportunity to participate in their Community Based Science Organizations project.  Using the resources provided, the Club began expanding the Mineral box idea and is working with the Anoka Schools to place general and Minnesota collections in that district.  The MMC is working with teachers to make the mineral boxes more useful and to help students discover that rocks are fun.

Recent Shows ...

The Club’s educational exhibits were held yearly up through 1996.  Then, interest waned as reasonably affordable venues became harder to find.  After much urging, the Club agreed to host the 2003 Midwest Federation convention, which meant hosting a three-day show.  A committee was set up and planning began for Great Lakes, Great Rocks -The Land of 10,000 Lakers.

After a successful 2003 event, the Club decided to continue hosting a sales and educational show, featuring the many facets of the rockhounding hobby.  The show committee ensures a mix of local and out of town dealers, as well as presentations, demonstrations, exhibits and an extensive “Kid’s Corner.”

Sadly, we were forced to cancel our 2020 show because of the pandemic. Thankfully, in September 2021 we were able to host an expanded show at the Minnesota State Fairgrounds. The 2021 show was a great success so we returned to the State Fairgrounds in 2022 and were rewarded with more vendors, larger crowds and more smiles.

History Updates


We began 2020 on a hopeful note. The year marked the start of the Club’s 75th year. We decided to publish a book covering key people and events over those 75 years and planned to end the year with a huge celebration. Our finances were solid and membership numbers were trending up.

Then the global COVID-19 pandemic arrived and the country (and world) started to shut down. The MMC was forced to cancel in-person meetings after March. Also, most Club 2020 field trips were cancelled as was the 2020 Annual Show.

The Board made the decision to invest in a Zoom account as a way of continuing to conduct Club business and to keep members connected via virtual meetings. We continued using social media, primarily Facebook, to keep the Club “top of mind “ in the rockhounding world. And we decided to focus more attention on our website through a major upgrade, which included more educational resources and the ability to take credit card payments for member dues and future merchandise sales.

Thankfully, these efforts paid off and our membership numbers grew throughout the pandemic. Members continued to participate in Zoom meetings in approximately the same numbers as those who had participated in person.

One positive that came out of the pandemic was a “forgiveness of member dues” for 2021. Because we were forced to cancel so many events that members were expecting, the Board voted to give all who were members before August 2020 (when the decision was made) free membership for 2021. And, for the first time in Club history, the membership year was changed from a calendar year basis to a rolling 12-month basis.

As 2020 ended, we completed work on our 75-year history with the publication on our website of “Our First 75 Years.” The book focuses on the people and the key events and decisions that have allowed the Club to remain vibrant throughout those many years.


2021 started as 2020 ended, with monthly meetings and separate “social hour” meetings via Zoom. However, in the spring, field trips returned and members eagerly took advantage of them. In August 2021, we re-introduced an activity from the Club’s past—a rock sale, swap and picnic, which was well attended. In September, we relaunched our Annual Show at a new venue—the Minnesota State Fairgrounds. The show drew high marks from the vendor community and the public. In October 2021 we were finally able to again meet in-person at our new meeting venue, the Roseville, MN Skating Center. Two other notable items from 2021: The Board changed the newsletter advertising policy by limiting advertising to members only and by allowing members to advertise free. Members approved the first dues increase in 12 years, effective January 2022.


The January 2022 meeting was to have resumed our tradition of starting the year with a potluck banquet. However, events conspired against us and we were not able to meet in-person until our March Demonstration Night program. In May we conducted our first Silent Auction since April 2019 and in June, held another rock sale, swap and picnic. Club sponsored field trips attracted about 150 members. Lead by a dedicated group of Field trip Leaders, they traveled to  Arizona, New Mexico, Iowa (Keokuk and Rockford), Minnesota (Cloquet, Moose Lake and Royalton), Thunder Bay, Canada, Colorado and Montana. Our September Annual Show at the Minnesota State Fairgrounds was one of our very best ever. The first fall meeting of 2022 was held in October at our newest meeting venue, the Creekside Community Center in Bloomington, MN. We finished 2022 strong, with solid finances and a growing membership base.
