Inflated balloons are being walked in from the edges of the field toward the gondola to be joined into clusters just prior to Dr. Piccard's take off. Dr. Jean Piccard was a University of Minnesota physicist and aeronautical engineer who believed it was possible to ascend into the stratosphere using many small cluster balloons rather than one large balloon. The experimental flight was sponsored by the Rochester Kiwanis Club and supported by local residents and students.
Assistants are holding individual inflated balloons at Soldiers Field while waiting for the signal to move towards the center and join the balloons into clusters for Dr. Jean Piccard's balloon ascension in the early hours of July 18, 1937.

The city of St. Paul drives piles above Phalen Creek in this photograph, taken to document improvements made to the St. Paul harbor and Upper Mississippi River. The overall project was completed in 1936.
This photograph documents progress made by the City of St. Paul on pile driving above Phalen Creek in early February 1936. Operations were temporarily suspended due to frigid temperatures. The pile driving was part of a project to improve the St. Paul harbor and Upper Mississippi River. The overall project was completed in 1936.
This photograph documents the pile driving underway as part of improvements to the St. Paul harbor and Upper Mississippi River, along the embankment below the new U.S. Post Office. The overall project was completed in 1936.
An embankment is placed behind the lower end of the retaining wall in St. Paul. The retaining wall and embankment were part of improvements to the St. Paul harbor and Upper Mississippi River in and around St. Paul, Minnesota in the mid-1930s. Work on the project was completed in 1936.
